Support `#[macro_use(name, ...)]`

This PR adds support for another form of the `macro_use` attribute: `#[macro_use(name, ...)]` ([reference]).

Note that this form of the attribute is only applicable to extern crate decls, not to mod decls.

bc03418127 Auto merge of #14746 - lowr:patch/associated-return-types, r=Veykril
Parse associated return type bounds

This PR implements parser support for associated return type bounds: `T: Foo<bar(): Send>`. This PR does not implement associated return types (`T::bar(): Send`) because it's not implemented even in rustc, and also removes `(..)`-style return type notation because it has been removed in rust-lang/rust#110203 (effectively reverting #14465).

I don't plan to proactively follow this unstable feature unless an RFC is accepted and my main motivation here is to remove no-longer-valid syntax `(..)` from our parser, nevertheless adding minimal parser support so anyone interested (as can be seen in #14465) can experiment it without rust-analyzer's syntax errors.

Expand more single ident macro calls upon item collection

Addresses https://github.com/rust-lang/rust-analyzer/pull/14781#issuecomment-1546201022

I believe this (almost) brings the number of unresolved names back to pre-#14781:

|r-a version|`analysis-stats compiler/rustc` (rust-lang/rust@69fef92ab2) |
|---|---|
|pre-#14781 (b069eb720b) | exprs: 2747778, ??ty: 122236 (4%), ?ty: 107826 (3%), !ty: 728 |
| #14781 (a7944a93a1) | exprs: 2713080, ??ty: 139651 (5%), ?ty: 114444 (4%), !ty: 730 |
| with this fix | exprs: 2747871, ??ty: 122237 (4%), ?ty: 108171 (3%), !ty: 676 |

(I haven't investigated on the increase in some numbers but hopefully not too much of a problem)

This is only a temporary solution. The core problem is that we haven't fully implemented the textual scope of legacy macros. For example, we *have been* failing to resolve `foo` in the following snippet, even before #14781 or after this patch. As noted in a FIXME, we need a way to resolve names in textual scope without eager expansion during item collection.

```rust
//- /main.rs crate:main deps:lib
lib::mk_foo!();
const A: i32 = foo!();
             //^^^^^^ unresolved-macro-call

//- /lib.rs crate:lib
#[macro_export]
macro_rules! mk_foo {
    () => {
        macro_rules! foo { () => { 42 } }
    }
}
```

35940bcda3 Remove identity_future from stdlib
This function/lang_item was introduced in #104321 as a temporary workaround of future lowering.
The usage and need for it went away in #104833.
After a bootstrap update, the function itself can be removed from `std`.

More core::fmt::rt cleanup.

- Removes the `V1` suffix from the `Argument` and `Flag` types.

- Moves more of the format_args lang items into the `core::fmt::rt` module. (The only remaining lang item in `core::fmt` is `Arguments` itself, which is a public type.)

Fixes https://github.com/rust-lang/rust-analyzer/issues/9055

The fix isn't that great, but we are kind of forced to do it the quick and hacky way right now since std has changed the `matches` macro to make use of this now. And for a proper fix we need to track hygiene for identifiers which is a long way off anyways

Add doc-alias based completion

Closes #14406.

I adapted the parsing code from the CfgExpr parsing code, maybe there's a better abstraction for both, or attribute parsing in general. It also includes `doc(hidden)`-parsing, which means it could replace the other function.
There are a few tests for parsing.

`process_all_names` changed the most, I added some docs there to explain what happens.

Many call sites just pass an empy vec to `add_path_resolution`'s `doc_aliases`, since either it doesn't make sense to pass anything (e.g. visibility completion) or I don't know where to get them from. Shouldn't really matter, as it will just not show aliases if the vec is empty and we can extend alias completion in these cases later.

I added two tests in `special.rs` for struct name completion (which was the main thing I wanted). I also tried function and field names, but these don't work yet. I want to add those in a follow-up PR.

Normalize associated types in paths in expressions

Part of #14393

When we resolve paths in expressions (either path expressions or paths in struct expressions), there's a need of projection normalization, which `TyLoweringContext` cannot do on its own. We've been properly applying normalization for paths in struct expressions without type anchor, but not for others:

```rust
enum E {
    S { v: i32 }
    Empty,
}

impl Foo for Bar {
    type Assoc = E;
    fn foo() {
        let _ = Self::Assoc::S { v: 42 };   // path in struct expr without type anchor; we already support this
        let _ = <Self>::Assoc::S { v: 42 }; // path in struct expr with type anchor; resolves with this PR
        let _ = Self::Assoc::Empty;         // path expr; resolves with this PR
    }
}
```

With this PR we correctly resolve the whole path, but we need some more tweaks in HIR and/or IDE layers to properly resolve a qualifier (prefix) of such paths and provide IDE features that are pointed out in #14393 to be currently broken.

Handle trait alias definitions

Part of #2773

This PR adds a bunch of structs and enum variants for trait aliases. Trait aliases should be handled as an independent item because they are semantically distinct from traits.

I basically started by adding `TraitAlias{Id, Loc}` to `hir_def::item_tree` and iterated adding necessary stuffs until compiler stopped complaining what's missing. Let me know if there's still anything I need to add.

I'm opening up this PR for early review and stuff. I'm planning to add tests for IDE functionalities in this PR, but not type-related support, for which I put FIXME notes.

Fix associated item visibility in block-local impls

Fixes #14046

When we're resolving visibility of block-local items...

> `self` normally refers to the containing non-block module, and `super` to its parent (etc.). However, visibilities must only refer to a module in the DefMap they're written in, so we restrict them when that happens. ([link])

 ...unless we're resolving visibility of associated items in block-local impls, because that impl is semantically "hoisted" to the nearest (non-block) module. With this PR, we skip the adjustment for such items.

Since visibility representation of those items is modified, this PR also adjusts visibility rendering in `HirDisplay`.

Beginning of MIR

This pull request introduces the initial implementation of MIR lowering and interpreting in Rust Analyzer.

The implementation of MIR has potential to bring several benefits:
- Executing a unit test without compiling it: This is my main goal. It can be useful for quickly testing code changes and print-debugging unit tests without the need for a full compilation (ideally in almost zero time, similar to languages like python and js). There is a probability that it goes nowhere, it might become slower than rustc, or it might need some unreasonable amount of memory, or we may fail to support a common pattern/function that make it unusable for most of the codes.
- Constant evaluation: MIR allows for easier and more correct constant evaluation, on par with rustc. If r-a wants to fully support the type system, it needs full const eval, which means arbitrary code execution, which needs MIR or something similar.
- Supporting more diagnostics: MIR can be used to detect errors, most famously borrow checker and lifetime errors,  but also mutability errors and uninitialized variables, which can be difficult/impossible to detect in HIR.
- Lowering closures: With MIR we can find out closure capture modes, which is useful in detecting if a closure implements the `FnMut` or `Fn` traits, and calculating its size and data layout.

But the current PR implements no diagnostics and doesn't support closures. About const eval, I removed the old const eval code and it now uses the mir interpreter. Everything that is supported in stable rustc is either implemented or is super easy to implement. About interpreting unit tests, I added an experimental config, disabled by default, that shows a `pass` or `fail` on hover of unit tests (ideally it should be a button similar to `Run test` button, but I didn't figured out how to add them). Currently, no real world test works, due to missing features including closures, heap allocation, `dyn Trait` and ... so at this point it is only useful for me selecting what to implement next.

The implementation of MIR is based on the design of rustc, the data structures are almost copy paste (so it should be easy to migrate it to a possible future stable-mir), but the lowering and interpreting code is from me.

fix: Don't expand macros in the same expansion tree after overflow

This patch fixes 2 bugs:

- In `Expander::enter_expand_id()` (and in code paths it's called), we never check whether we've reached the recursion limit. Although it hasn't been reported as far as I'm aware, this may cause hangs or stack overflows if some malformed attribute macro is used on associated items.
- We keep expansion even when recursion limit is reached. Take the following for example:

  ```rust
  macro_rules! foo { () => {{ foo!(); foo!(); }} }
  fn main() { foo!(); }
  ```

  We keep expanding the first `foo!()` in each expansion and would reach the limit at some point, *after which* we would try expanding the second `foo!()` in each expansion until it hits the limit again. This will (by default) lead to ~2^128 expansions.

  This is essentially what's happening in #14074. Unlike rustc, we don't just stop expanding macros when we fail as long as it produces some tokens so that we can provide completions and other services in incomplete macro calls.

This patch provides a method that takes care of recursion depths (`Expander::within_limit()`) and stops macro expansions in the whole macro expansion tree once it detects recursion depth overflow. To be honest, I'm not really satisfied with this fix because it can still be used in unintended ways to bypass overflow checks, and I'm still seeking ways such that misuses are caught by the compiler by leveraging types or something.

Fixes #14074
