[FIR] KT-54410: Report API_NOT_AVAILABLE for classifiers

Callable symbols with SinceKotlin are filtered out by a
resolution stage, but in K1 classifiers and property accessors
report API_NOT_AVAILABLE. K2 filters out properties with
unavailable accessors, but does nothing for classifiers.
This change fixes it.
