31006930 - Tests: Use `REQUIRES: maccatalyst_support` instead of `REQUIRES: OS=maccatalyst` whereever possible to broaden coverage for MacCatalyst specific tests.

These tests did not need the runtime OS to be MacCatalyst; they need the compiler to support `macabi` triples (e.g. `-target x86_64-apple-ios13.1-macabi`). Also, fix a few tests that had rotted because they had not been running in CI. Resolves rdar://90937822
