Remove dead test files and update findUnusedTestFiles

Remove a few .bad files whose .futures were removed in #17353 and #18724, and a .compopts file that appears never to have been used.

The affected directories pass testing.

Update findUnusedTestFiles to skip all .notest files in test/mason due to how often these are to skip directories created at runtime. Also handle a few more special cases in test/distributions/robust/arithmetic/.
