Auto merge of #16356 - Veykril:sysroot-metadata, r=Veykril
internal: Add unstable config for loading the sysroot sources via `cargo metadata` cc https://github.com/rust-lang/rust-analyzer/issues/7637 This takes the approach of having `cargo metadata` generate a lock file that we then delete again, hence why this is behind a flag. If people need this for their workflow they can just enable it, if not, they are probably better off keeping it disabled.
