Auto merge of #140145 - Zoxc:job-server-proxy, r=SparrowLii
Add a jobserver proxy to ensure at least one token is always held This adds a jobserver proxy to ensure at least one token is always held by `rustc`. Currently with `-Z threads` `rustc` can temporarily give up all its tokens, causing `cargo` to spawn additional `rustc` instances beyond the job limit. The current behavior causes an issue with `cargo fix` which has a global lock preventing concurrent `rustc` instances, but it also holds a jobserver token, causing a deadlock when `rustc` gives up its token. That is fixed by this PR. Fixes https://github.com/rust-lang/rust/issues/67385. Fixes https://github.com/rust-lang/rust/issues/133873. Fixes https://github.com/rust-lang/rust/issues/140093.
