K2/Java: fix processing of built-in with value parameters to be erased in Java

In this commit we started to create and process a hidden copy
for a built-in functions, which value parameters are erased in Java,
in case we have an accidental Java override which value parameters
are not erased.

In this situation attempt to override such a Java override in Kotlin
again will lead to inaccessible functions
(see changes in containsAndOverload.fir.kt)
