K2: Fix false-positive on delegated constructor call of outer class
See callingOuterGenericClassConstructorWithSelfTypes.kt
Previously, for A<B>(""), we used substituted constructor
where `X` was substituted with `B` (or `A<X>.B`).
But when resolving the call for constructor, we use `X`
as a type variable of the call, thus in some positions
we used `X` as TV (Xv in the comments) and somewhere `X` as a type
parameter, thus leading to contradictions (see clarifying comment).
The idea of the fix is simply repeating of the regular (not delegated)
constructor call resolution:
- We substitute only type parameters of outer class
- All the declared parameters of the callee are being checked
through regular resolution & inference mechanisms.
NB: Diagnostic only being reported on arguments because there
when we add `String <: Any` constraint it fails due to existing
contradiction in the CS.
Without the argument/parameter the error is just being lost, but that's
a different story (seeKT-65224).
