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.
