Subject: [PATCH] bootstrap: add rust-toolchain to the root directory

Helps with https://github.com/rust-lang/rust/issues/94829.

This doesn't solve "bootstrap uses beta rustc but nightly rustfmt",
but in practice there should be very little difference between two.
Users can still override the toolchain used with `cargo +nightly` or similar.
