fix: don't replace default members' body
cc #12779, #12821
addresses https://github.com/rust-lang/rust-analyzer/pull/12821#issuecomment-1190157506
`gen_trait_fn_body()` only attempts to implement required trait member functions, so we shouldn't call it for `Implement default members` assist.
This patch also documents the precondition of `gen_trait_fn_body()` and inserts `debug_assert!`, but I'm not entirely sure if the assertions are appropriate.
- 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

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.
fix: Fix restart server duplicating language clients
Reverts 03a62c180e
vscode-languageclient@8.0.0-next.15 and beyond changed the behaviour of language clients to be automatically started if a request comes in while they are not running. Currently when we restart the server via the restart command we recreate the language client, which causes VSCode to restart the stopped server, effectively duplicating our language clients...
Reverting the commit is simpler right now, the proper fix would be to only create a language client once and then use the `restart` functionality on it instead.

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.
