The current rust-version = "1.63" was inherited from rayon, but it
doesn't make sense to limit this in the compiler workspace. Having any
setting at all has effects on tools like cargo info that try to infer
the MSRV when the workspace itself doesn't specify it. Since we are the
compiler, our only MSRV is whatever bootstrapping requires.

For example, I was confused why cargo info bindgen-cli was giving me an older version while I happened to be in my rust worktree, even though that crate is not anywhere in our lockfiles.
