11540: fix: Resolve private fields in type inference r=flodiebold a=Veykril
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/10253#issuecomment-920962927
(the same issue probably exists for method calls, but I think fixing that might be trickier)
Visibility checks were introduced in https://github.com/rust-analyzer/rust-analyzer/issues/7841 for autoderef to work properly, so now we just record the first field we find unconditionally, and then overwrite it if autoderef manages to find another field in a later cycle.
