Disregard annotation params for stale dataclass detection

Annotation processor seens annotation args with constants already inlined,
making it challenging to compare to the souce-generated metadata that contains
initial expressions.

For now just ignoring args for all non-DataClass annotations to prevent false positives

Test: . frameworks/base/tests/Codegen/runTest.sh
