[NI] CST: add preemptive recursion detection

Browse Source 
For single super type constructor create star projection argument when types for that argument are equal to the original types.
Captured star projections are replaced with their corresponding supertypes during this check.
Skip check for `in` parameters, for which recursive cst calculation does not happen.
Adjust constant in fallback recursion condition.
