Auto merge of #99756 - fasterthanlime:ra-sync-and-pms-component, r=Mark-Simulacrum
Sync `rust-analyzer`, add `rust-analyzer-proc-macro-srv` binary to Rustc component As discussed earlier with `@jyn514` and `@pietroalbini,` I'm also going to use this PR to have `dist::Rustc` build the `rust-analyzer-proc-macro-srv` binary introduced in: * rust-lang#12871
