Fix inconsistencies in no-chachapoly test

The original goal (#5072) was to run
a test with ChaChaPoly disabled in PSA. It was actually implemented with GCM
also partially disabled (legacy GCM enabled but PSA GCM disabled), which
distracted from the objective. It's actually useful to test both with and
without GCM, so test both. Don't test inconsistencies between legacy and PSA
support because that's not a common case and not one we have particular
reasons to test.
