Rollup merge of #83368 - jyn514:download-if-unchanged, r=Mark-Simulacrum
Add `download-rustc = "if-unchanged"`

This allows keeping the setting to a fixed value without having to
toggle it when you want to work on the compiler instead of on tools.

This sets `BOOTSTRAP_DOWNLOAD_RUSTC` in bootstrap.py so rustbuild doesn't have to try and replicate its logic.

Helps with https://github.com/rust-lang/rust/issues/81930.
