feat: Use spans for builtin and declarative macro expansion errors
This should generally improve some error reporting for macro expansion errors. Especially for `compile_error!` within proc-macros

This is an preparation for https://github.com/rust-lang/rust-analyzer/issues/17719.
```rust
use std::future::Future;
trait DesugaredAsyncTrait {
fn foo(&self) -> impl Future<Output = usize> + Send;
fn bar(&self) -> impl Future<Output = usize> + Send;
}
struct Foo;
impl DesugaredAsyncTrait for Foo {
fn foo(&self) -> impl Future<Output = usize> + Send {
async { 1 }
}
//
async fn bar(&self) -> usize {
1
}
}
fn main() {
let fut = Foo.bar();
fn _assert_send<T: Send>(_: T) {}
_assert_send(fut);
}
```
If we don't distinguish `async` or not. It would be confusing to generate sugared version `async fn foo ....` and original form `fn foo` for `async fn in trait` that is defined in desugar form.
fix: let glob imports override other globs' visibility
Follow up to #14930Fixes#11858Fixes#14902Fixes#17704
I haven't reworked the code here at all - I don't feel confident in the codebase to do so - just rebased it onto the current main branch and fixed conflicts.
I'm not _entirely_ sure I understand the structure of the `check` function in `crates/hir-def/src/nameres` tests. I think the change to the test expectation from #14930 is correct, marking the `crate::reexport::inner` imports with `i`, and I understand it to mean there's a specific token in the import that we can match it to (in this case, `Trait`, `function` and `makro` of `pub use crate::defs::{Trait, function, makro};` respectively), but I had some trouble understanding the meaning of the different parts of `PerNs` to be sure.
Does this make sense?
I tested building and using RA locally with `cargo xtask install` and after this change the documentation for `arrow_array::ArrowPrimitiveType` seems to be picked up correctly!
The issue occurs because in some configurations of traits where one of them has Deref as a supertrait, RA's type inference algorithm fails to resolve the Deref::Target type, and instead uses a TyKind::BoundVar (i.e. an unknown type). This "autoderefed" type then incorrectly acts as if it implements all traits in scope.
The fix is to re-apply the same sanity-check that is done in iterate_method_candidates_with_autoref(), that is: don't try to resolve methods on unknown types. This same sanity-check is now done on each autoderefed type for which trait methods are about to be checked. If the autoderefed type is unknown, then the iterating of the trait methods for that type is skipped.
Includes a unit test that only passes after applying the fixes in this commit.
Includes a change to the assertion count in test syntax_highlighting::tests::benchmark_syntax_highlighting_parser as suggested by Lukas Wirth during review.
Includes a change to the sanity-check code as suggested by Florian Diebold during review.
feat: add preliminary support for `+ use<..>` `precise_capturing` syntax
## Summary
This PR adds basic support for the following syntax.
```rs
fn captures<'a: 'a, 'b: 'b, T>() -> impl Sized + use<'b, T> {}
// ~~~~~~~~~~~~~~~~~~~~~~~
// This opaque type does not capture `'a`.
fn outlives<'o, T: 'o>(_: T) {}
fn caller<'o, 'a, 'b: 'o, T: 'o>() {
// ~~
// ^ Note that we don't need `'a: 'o`.
outlives::<'o>(captures::<'a, 'b, T>());
}
```

internal: add more output to the status command
Bit of a lazy change, but this is was pretty handy. I think I should clean up the configuration into something a bit more legible (maybe serialize as JSON?), but I think this is a good enough starting point that we might as well start asking people for it in issue reports.
Add method `Impl::all_in_module(…)` for allowing more localized querying
This PR is motivated by an [outside use](https://github.com/regexident/cargo-modules) of the `ra_ap_hir` crate that would benefit from being able to more efficiently query for all impls of a given module (instead of having to query for its parent crate's impls and then filtering on `impl_hir.module(db) == module_hir`).
I have the suspicion that the code as is won't quite work for file-level modules, since those don't have a block, afaict, but with all the crate-rename and version shenanigans around the `ra_ap_` release process I haven't yet been able to figure out how to patch a `ra_ap_` dependency from a third-party crate (let alone how to test this from inside of `rust-analyzer`), so haven't been able to actually run and test this. 😔
Any hints on how to make this (i.e. the code itself, as well as the testing) work are more than welcome!
chore: remove `UnindexinedProject` notification
This PR is split out from https://github.com/rust-lang/rust-analyzer/pull/17246/ (and contains its changes, which is a little annoying from a review perspective...). I'd like to land this change a week or so after #17246 lands in order to give any users of the unindexed project notification time to adopt migrate.
minor : fixes for ratoml module
This is a follow-up PR to #17058.
- Parse errors are reflected as such by defining a new variant called `ConfigError::ParseError`
- New error collection has been added to store config level agnostic errors.
EDIT : Some things that this PR promised to solve are removed and will be addressed by other PRs
