Merge #5682

5682: Add an option to disable diagnostics r=matklad a=popzxc

As far as I know, currently it's not possible to disable a selected type of diagnostics provided by `rust-analyzer`.

This causes an inconvenient situation with a false-positive warnings: you either have to disable all the diagnostics, or you have to ignore these warnings.

There are some open issues related to this problem, e.g.: https://github.com/rust-analyzer/rust-analyzer/issues/5412, https://github.com/rust-analyzer/rust-analyzer/issues/5502

This PR attempts to make it possible to selectively disable some diagnostics on per-project basis.
