rust Move ambient gdb discovery from compiletest to bootstrap

Follow-up to https://github.com/rust-lang/rust/pull/148099

This code takes the compiletest code for discovering an “ambient” gdb in the user's path, and moves it to bootstrap.

One of the eventual goals is to allow compiletest to assume that if it has been asked to run the debuginfo-gdb suite, then it must have been passed an explicit --gdb, though we aren't quite there yet.

This PR was rebased onto a different main commit. Here's a range-diff highlighting what actually changed.

Rebasing is a normal part of keeping PRs up to date, so no action is needed—this note is just to help reviewers.
