Merge #7907

7907: Autoderef with visibility r=cynecx a=cynecx

Fixes https://github.com/rust-analyzer/rust-analyzer/issues/7841.

I am not sure about the general approach here. Right now this simply tries to check whether the autoderef candidate is reachable from the current module. ~~However this doesn't exactly work with traits (see the `tests::macros::infer_derive_clone_in_core` test, which fails right now).~~ see comment below
