fix: Acknowledge `pub(crate)` imports in import suggestions
rust-analyzer has logic that discounts suggesting `use`s for private imports, but that logic is unnecessarily strict - for instance given this code:
```rust
mod foo {
pub struct Foo;
}
pub(crate) use self::foo::*;
mod bar {
fn main() {
Foo$0;
}
}
```
... RA will suggest to add `use crate::foo::Foo;`, which not only makes the code overly verbose (especially in larger code bases), but also is disjoint with what rustc itself suggests.
This commit adjusts the logic, so that `pub(crate)` imports are taken into account when generating the suggestions; considering rustc's behavior, I think this change doesn't warrant any extra configuration flag.
Note that this is my first commit to RA, so I guess the approach taken here might be suboptimal - certainly feels somewhat hacky, maybe there's some better way of finding out the optimal import path 😅

fix: try obligation of `IndexMut` when infer
Closes#15842.
This issue arises because `K` is ambiguous if only inferred from `Index` trait, but is unique if inferred from `IndexMut`, but r-a doesn't use this info.
fix: Correctly set and mark the proc-macro spans
This slows down analysis by 2-3s on self for me unfortunately (~2.5% slowdown)
Noisy diff due to two simple refactoring in the first 2 commits. Relevant changes are [7d762d1](7d762d18ed) and [1e1113c](1e1113cf5f) which introduce def site spans and correct marking for proc-macros respectively.
