[FIR] Improve approximation of captured types

Browse Source 
- Handle flexible types in recursion check
- Handle intersected supertypes separately
- Make check when not to approximate captured types in type argument
  position more fine-grained.
  Only apply it to case when the captured type is replaced by a star
  projection.
  All other cases are handled by recursive calls to
  approximateCapturedType
