K2: fix enhancement building for Java methods with type parameters

Before this commit, we copied each type parameter during method
enhancement, while not copying the symbol. This led to symbol clashes
in MPP scenarios and various other problems.

Now we create a fully-functional type parameter copy in enhancement
and perform a substitution of old type parameters with new ones
in receiver type, value parameter types, return type,
and type parameter upper bounds.
