proc_macro/bridge: send diagnostics over the bridge as a struct
This removes some RPC when creating and emitting diagnostics, and
simplifies the bridge slightly.
After this change, there are no remaining methods which take advantage
of the support for `&mut` references to objects in the store as
arguments, meaning that support for them could technically be removed if
we wanted. The only remaining uses of immutable references into the
store are `TokenStream` and `SourceFile`.

- use `path` instead of `paths`
- don't mark rust-analyzer as an optional tool
- print the cargo command that's run in the proc-macro-test build script
this originally was part of a change to fix `test --stage 0 rust-analyzer`,
but I'm going to leave that for a separate PR so it's easier to review.
fix: Don't add braces to 'if' completion in match guard position
fixes#12823
Is this what you were thinking of here, `@Veykril` ? I haven't done any work on completions before, so I could definitely be misunderstanding the issue.
internal: Use ItemTree for variant, field and module attribute collection in attrs_query
Less parsing = very good, should speed up lang item collection as that basically probes attributes of all enum variants which currently triggers parsing
Not fond of how this is searching for the correct index, ideally we'd map between HIR and item tree Id here but I am not sure how, storing the item tree ids in the HIR version doesn't work due to the usage of `Trace`...
Otherwise, fall back to the multi ABI scheme, except in testing, where
it becomes a hard error.
This should make it possible to use a rustup-provided rust-analyzer with
proc macro dylibs compiled by older rustcs, and it'll also catch changes
to the format of `rustc --version` or the `.rustc` section that would
make them impossible to compare for equality.
