Subject: rustbuild: Tweak for vendored dependencies

A few changes are included here:

* The `winapi` and `url` dependencies were dropped. The source code for these
  projects is pretty weighty, and we're about to vendor them, so let's not
  commit to that intake just yet. If necessary we can vendor them later but for
  now it shouldn't be necessary.

* The `--frozen` flag is now always passed to Cargo, obviating the need for
  tidy's `cargo_lock` check.

* Tidy was updated to not check the vendor directory

Closes #34687
