Error message contains $crate instead of crate name

[Aaron1011]

Since #82069 was merged, the 'this error originates in macro <name>) messages sometimes contain $crate, instead of the actual crate name.

For example:

rust/src/test/ui/bound-suggestions.stderr

Line 8 in 9daf546

= note: this error originates in the macro `$crate::format_args_nl` (in Nightly builds, run with -Z macro-backtrace for more info)

We should resolve these $crate identifiers to the actual crate name before displaying them to the user.
