Extract common logic into AbstractTypeConstructor

Browse Source 
Mostly it's about detecting loops in supertypes

Test data changes:
- Loops are being disconnected in Java classes too
- functions.kt: loops disconnection mechanism runs supertypes calculation,
so when we start check T it forces F' supertypes calculation, that ends
with CYCLIC_GENERIC_UPPER_BOUND reported on F
