Fix late-bound lifetime closure ICEs in HIR typeck and MIR borrowck

During HIR typeck, we need to teach astconv to treat late-bound regions within a closure body as free, fixing escaping bound vars ICEs in both of the issues below.

However, this then gets us to MIR borrowck, which itself needs to be taught how to instantiate free region vids for late-bound regions that come from items that _aren't_ the typeck root (for now, just closures).

Add track_caller to some Lock methods

Would have helped to diagnose rust-lang#103844.

Remove rustdoc clean::Visibility type

Fixes rust-lang#90852.

Follow-up of rust-lang#103690.

This PR completely removes the rustdoc `clean::Visibility` type to use the `rustc_middle` one instead. I don't think there will be any impact on perf.

Fix ICE when negative impl is collected during eager mono

```rust
trait Foo {
    fn foo() {}
}

impl !Foo for () {}
```

This code will currently cause an ICE when mono collection mode is "eager" (with `-C link-dead-code=y` or `-Z print-mono-items=eager`.

Remove unused argument from `throw_unresolved_import_error`

`throw_unresolved_import_error` does not need the second argument.
