Revert compiletest new-executor, to re-land without download-rustc

[Zalathar]

Revert #139998 because the original merge triggered download-rustc, which messes with test metrics and prevents us from properly comparing them before/after the change.

The plan is to re-land this PR as-is, combined with a trivial compiler change to avoid download-rustc and get proper test metrics for comparison.

This reverts commit be181dd, reversing changes made to 645d0ad.

Actually, let's not roll this up either in case it affects test diffs in a rollup (I don't expect that it does, but just in case). Giving this a higher priority to minimize number of merged PRs potentially affected (again, I don't expect differences but just to be extra safe).

@bors rollup=never p=5 (revert to previous libtest executor)

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
