[clang] [tests] Split up darwin-macatalyst test (PR #162358)

[Cyndy Ishida via cfe-commits]

https://github.com/cyndyishida created https://github.com/llvm/llvm-project/pull/162358

The way this test was constructed made it difficult to test downstream divergence correctly; instead split the error case.
