Bug 1928709 - Remove build/tests/cram, r=firefox-build-system-reviewers,ahochheiden,nalexander

This is being removed because:
1. It it the last remaining cram test in-tree
2. It doesn't run in any CI tasks
3. It doesn't appear to be a particularly high value test

Once this is removed, the cramtest harness can also be removed.
