[IR] Fix annotation arguments comparison when expression is expect enum

...actualized via typealias. This caused false-positive report of
`ACTUAL_ANNOTATION_CONFLICTING_DEFAULT_ARGUMENT_VALUE`.
In such case it's incorrect to compare signatures, because classes have
different `ClassId`s. Instead, classes could be compared using
`areCompatibleExpectActualTypes` which actualizes both types, and
then enum value names compared.
