Use wrappers around java.util.* to emulate kotlin.collection.* behaviour

Browse Source 
Backend: If kotlin class extends kotlin.collection.List
    write it as it's super interface (light class mode only)
IDE: Provide wrapper classes to java resolve
    that try to emulate backend behaviour

For example if kotlin class implements kotlin.collections.Map,
    we provide a superinterface that has abstract 'getEntries' method
    and 'entrySet' method that is considered default.
In reality all those methods are generated in the class itself.

In IDE supporting this case without hacks is not feasible performance-wise
    since kotlin.collection.* may not be an immediate supertype and we need
    to compute all supertypes just to calculate own methods of the class
