8065: Better handling of block doc comments r=Veykril a=Veykril
Moves doc string processing to `Attrs::docs`, as we need the indent info from all comments before being able to know how much to strip
Closes#7774

8063: couple clippy::complexity fixes r=matklad a=matthiaskrgr
avoid redundant `.into()` calls to convert T into identical T (`let x: String = String::from("hello").into();`)
use `if let Some(x)` instead of `.is_some()` + `.unwrap()`
don't clone Copy types
remove redundant wrapped ?s: `Some(Some(3)?)` can just be `Some(3)`
use `.map(|x| y)` instead of `and_then(|x| Some(y)` on `Option`s

7900: show function params in completion detail r=matklad a=JoshMcguigan
This resolves#7842 by updating the detail for function completions from `-> T` to `fn(T, U) -> V`. I added an expicit unit test for this, `ide_completion::render::fn_detail_includes_args_and_return_type`, which passes.
Lots of other unit tests fail (~60 of them) due to this change, although I believe the failures are purely cosmetic (they were testing the exact format of this output). I'm happy to go update those tests, but before I do that I'd like to make sure this is in fact the format we want for the detail?
edit - I realized `UPDATE_EXPECT=1 cargo test` automatically updates `expect!` tests. Big 👍 to whoever worked on that! So I'll go ahead and update all these tests soon. But I still would like to confirm `fn(T, U) -> V` is the desired content in the `detail` field.

7970: Fix incorrect diagnostics for failing built in macros r=jonas-schievink a=brandondong
**Reproduction:**
1. Use a built in macro in such a way that rust-analyzer fails to expand it. For example:
**lib.rs**
```
include!("<valid file but without a .rs extension so it is not indexed by rust-analyzer>");
```
2. rust-analyzer highlights the macro call and says the macro itself cannot be resolved even though include! is in the standard library (unresolved-macro-call diagnostic).
3. No macro-error diagnostic is raised.
**Root cause for incorrect unresolved-macro-call diagnostic:**
1. collector:collect_macro_call is able to resolve include! in legacy scope but the expansion fails. Therefore, it's pushed into unexpanded_macros to be retried with module scope.
2. include! fails at the resolution step in collector:resolve_macros now that it's using module scope. Therefore, it's retained in unexpanded_macros.
3. Finally, collector:finish tries resolving the remaining unexpanded macros but only with module scope. include! again fails at the resolution step so a diagnostic is created.
**Root cause for missing macro-error diagnostic:**
1. In collector:resolve_macros, directive.legacy is None since eager expansion failed in collector:collect_macro_call. The macro_call_as_call_id fails to resolve since we're retrying in module scope. Therefore, collect_macro_expansion is not called for the macro and no macro-error diagnostic is generated.
**Fix:**
- In collector:collect_macro_call, do not add failing built-in macros to the unexpanded_macros list and immediately raise the macro-error diagnostic. This is in contrast to lazy macros which are resolved in collector::resolve_macros and later expanded in collect_macro_expansion where a macro-error diagnostic may be raised.

7778: Fix lowering trailing self paths in UseTrees r=Veykril a=Veykril
Noticed that hovering over `self` in a use tree like `use foo::bar::{self}` showing documentation and such for the current module instead of `bar`.

7804: Introduce TypeCtor::Scalar r=lnicola a=Veykril
`TypeCtor::Int(..) | TypeCtor::Float(..) | TypeCtor::Char | TypeCtor::Bool` => `TypeCtor::Scalar(..)`, in this case we can actually just straight up use `chalk_ir::Scalar` already since its just a POD without any IDs or anything.

7426: Create all `ModuleId`s through a `DefMap` method r=jonas-schievink a=jonas-schievink
`ModuleId` needs to be able to represent blocks, and only the
associated `DefMap` will know how to construct that `ModuleId`

7359: ItemTree: store a mapping from blocks to inner items r=jonas-schievink a=jonas-schievink
To do name resolution within block expressions, we need to know which inner items are located inside each block expression. This adds such a mapping to `ItemTree`, replacing the previous one, which was seemingly unused other than to access all the inner items.
This also assigns `AstId`s to block expressions, which is needed to store the mapping in salsa.

7336: Rename `CrateDefMap` to `DefMap` r=matklad a=jonas-schievink
I propose handling local items by computing a `DefMap` for every block expression, using the regular (early) name resolution algorithm. The result of that will be a `DefMap` that has a reference to the parent `DefMap`, which is either the one computed for the containing block expression, or the crate's root `DefMap`. Name resolution will fall back to a name in the parent `DefMap` if it cannot be resolved in the inner block.
The `DefMap`s computed for block expressions will go through a separate query that can be garbage-collected much more aggressively, since these `DefMap`s should be cheap to compute and are never part of a crate's public API.
The first step towards that is to make `CrateDefMap` not specific to crates anymore, hence this rename (if this plans sounds reasonable).

7276: Remove map module from la-arena public API r=lnicola a=arzg
It’s unlikely that more items will be added to the module, so it’s simpler for users if `ArenaMap` is re-exported and the module made private.
This doesn’t compile for the same reason that #7275 doesn’t:
> This pull request doesn’t compile because dependencies on la-arena go through crates.io, so existing dependencies on the crate are referencing an old version. As such, this PR will only compile once a new la-arena version has been published.
