[FIR] Don't generate Any.{toString, equals, hashCode} for expect value classes in metadata

^KT-64121 Fixed
Review: https://jetbrains.team/p/kt/reviews/13495/timeline

If we generate these declarations then the compiler sees Any.{toString,
equals, hashCode} non-synthetic declarations of common metadata and
reports false positive ACTUAL_MISSING during intermediate (HMPP)
metadata compilation.
