[AA] Handle KtTypeReference children in CompileTimeConstantProvider

CompileTimeConstantProvider could receive a reference expression,
whose grandparent is KtTypeReference (seen that in UAST inspection).
FIR would not contain anything explicit for this reference,
FirResolvedTypeRef would be received as the nearest parent.
Of course, in this case, there could be no compile time constant anyway.
