JVM IR: use correct owner for callable references in optimized multifile classes

The owner should always be the facade class, because the part class is
package-private and will be inaccessible from other package.

Note that in the old backend, function references already do have the
facade as the owner correctly, but property references don't, this is
reported as KT-37972.
