Various cabal-testsuite improvements (#10225)

* Improve bat scripts for CCompilerOverride * Ensure Windows tests can cleanup the temp directory * Implement `flaky` combinator * Remove outdated tests * Remove broken tests These tests were testing for messages that were removed with the `cabal check` rework. * Make `skip` and `broken` messages uniform * Mark flaky tests * Re-enable DeterministicTrivial * Fix MacOS canonical paths * Extend cabal-testsuite readme with `flaky` * Skip non-terminating tests in Windows CI --------- Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com>
