7059: Special case $_ in meta var instead of treat it as ident in mbe r=lnicola a=edwin0cheng
In #6929, we treat '_' as an ident but rustc is only allow it in some special places (e.g. meta var in mbe , type, pat etc).
This PR rollback that and we only make '$_' works in meta var matching.
Fixes#7056

6820: Pass the crate environment to proc macros r=jonas-schievink a=jonas-schievink
In theory, fixes https://github.com/rust-analyzer/rust-analyzer/issues/6696.
This seems to result in these obscure crashes for some reason:

7047: Add force_show_panics flag for proc-macro bridge r=jonas-schievink a=edwin0cheng
https://github.com/rust-lang/rust/pull/75082 and https://github.com/rust-lang/rust/pull/76292 added a new flag in `proc_macro::Bridge` such that the ABI was changed. These ABI changing are the reason of some weird panics which caused #6880 and maybe related to the panic mentioned in #6820.
These changes are landed on rust stable 1.48 so I think it is okay to apply it now.

Assist vs UnresolvedAssist split doesn't really pull its weight. This
is especially bad if we want to include `Assist` as a field of
diagnostics, where we'd have to make the thing generic.

Implements general navigation for labels, goto def, rename and gives labels their own semantic highlighting class.
