7055: Install rustfmt if needed during formatting request r=matklad a=kinnison
In order to fix#6052 and to fix#4249 this PR installs `rustfmt` using `rustup` if `rustfmt --help` fails.
In theory we ought to memoise the attempts (both the `--help` and the installation) so that we don't keep retrying something which will fail (e.g. if nightly is missing rustfmt), but this is a first-pass for opinions.
In order to make it possible to notify the user of what happened, I added a facility for `GlobalStateSnapshot` to send *messages* to the client indicating what happened. There may be a cleaner way to do this as well but I wasn't sure exactly what might be best given this is my first time in this codebase.
It may be worth, longer term, working with `rustup` to provide a way to detect a missing component binary since `rustup` returns `1` if `rustfmt` is not installed, which is not ideal.

In an attempt to fix#6052 and #4249 this attempts to detect
if rustfmt is a rustup proxy which isn't installed, and reports
the error message to the user for them to fix.
In theory this ought to be memoised but for now it'll do as-is.
Future work might be to ask the user if they would like us to
trigger the installation (if possible).

Previously the inserted text was always `..Default::default()` which ends up as `...Default::default()`
if `.` was typed. Now checks if the current token is `.` and inserts `.Default::default()`
if it is, so `..Default::default()` is correctly completed.
Fixes#6969
7091: Add an option for extra env vars in the Code extension r=lf- a=lf-
I was debugging some issues with the RA extension around getting `cargo check` to work and it was particularly frustrating to get the RA_LOG variable set on the server since I had to change it in a login file. This should make that easier.

7088: Smarter bracketed `use` diagnostic r=lnicola a=AdnoC
Closes https://github.com/rust-analyzer/rust-analyzer/issues/4531
Makes it so that if a bracketed use statement contains a comment inside the braces, no "Unnecessary braces in use statement" diagnostic is shown.

7083: Refactor mbe parsing code r=edwin0cheng a=edwin0cheng
Inspire by #5426 , this PR refactor out the parsing code such that it only parsed on `mbe::Rule`, but not on invocations.
However, it just improve the overall performance unnoticeablely :(

7077: Avoid a couple of allocations r=Veykril a=lnicola
r? @Veykril
TBH I'm not sure this is worth it, but the other `Query` was already taking a `String`.

7064: Ignore qualifiers when doing autoimport completions lookup r=lnicola a=SomeoneToIgnore
A follow-up of https://github.com/rust-analyzer/rust-analyzer/pull/6918#issuecomment-748511151 and the PR itself.
Tweaks the `import_map` query api to be more flexible with the ways to match against the import path and now fuzzy imports search in names only.
This had improved the completion speed for me locally in ~5 times for `fuzzy_completion` span time, but please recheck me here.
IMO we're fast and presice enough now, so I've added the modules back to the fuzzy search output.
Also tweaks the the expect tests to display functions explicitly, to avoid confusing "duplicate" results.

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
