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 panic with closure inside array len
I was working on #15947 and found out that we panic on this test:
```
fn main() {
let x = [(); &(&'static: loop { |x| {}; }) as *const _ as usize]
}
```
This PR fixes the panic. Closures in array len are still broken, but closure in const eval is not stable anyway.
