Report JVM signature clashes from JVM_IR

Also:

* Do not rename public ABI fields
This includes backing fields for const, lateinit, @JvmField properties,
and instance fields for objects.

* FAKE_OVERRIDE declarations for static members of parent Java classes
Required to report cases when a Kotlin function accidentally overrides
Java class member.
