[Commonizer] Don't commonize deprecated functions

1. All functions marked with @Deprecated from Kotlin/Native platform libraries
have DeprecationLevel.ERROR, and therefore practically can not be used by
a developer in their code. So, it does not make sence to keep such
declarations in commonized libraries.

2. Commonization of such functions would also require commonization of
annotations with nested annotations as const values (ex:
@Deprecated(level = DeprecationLevel.ERROR), where both @Deprecated
and DeprecationLevel are annotation classes). This is not implemented yet.
