rust-analyzer's RUSTC_WRAPPER unconditionally succeeds `cargo check`
invocations tripping up build scripts using `cargo check` to probe for
successful compilations. To prevent this from happening the RUSTC_WRAPPER
now checks if it's run from a build script by looking for the
`CARGO_CFG_TARGET_ARCH` env var that cargo sets only when running build
scripts.
When r-a starts up, it starts switching the workspace before all vfs
events have been processed which causes us to switch workspace multiple
times until all vfs changes have been processed. This scales with the
size of the project and its dependencies. If workspace files from
dependencies as well as the sysroot get loaded, we shouldn't switch
the workspace as those have no impact on the project workspace.
feat: Only flycheck workspace that belongs to saved file
Supercedes https://github.com/rust-lang/rust-analyzer/pull/11038
There is still the problem that all the diagnostics are cleared, only clearing diagnostics of the relevant workspace isn't easily doable though I think, will have to dig into that
feat: Spawn a proc-macro-srv instance per workspace

The idea is to have each server be spawned with the appropriate toolchain, that way workspaces with differing toolchains shouldn't suffer from proc-macro abi mismatches.
Rationale: Merge commits will probably end up in
`rust-lang/rust-analyzer` when doing "rust=>ra" syncs anyway.
It could be changed to only check for merge commits in non-sync PRs,
but it's "probably not worth the hassle"
This adds an `in-rust-tree` feature that will be enabled when
rust-analyzer is built from `rust-lang/rust`. Due to the way
"git subtree" works, that test _will_ find merge commits and
fail, so we simply skip it.
Add simple support for completion item details
Supercedes https://github.com/rust-lang/rust-analyzer/pull/9891
This doesn't yet really implement anything new, it just adds the scaffolding for the protocol conversion
fix: make file watcher config a drop-down (and clarify the options)
Fixes https://github.com/rust-lang/rust-analyzer/issues/12794
Also renames "notify" to "server", since that's clearer ("notify" is still accepted for compatibility).
