      public boolean hasPolymorphicSignature(Scope scope)
      Identifies whether the method has Polymorphic signature based on jls-15.12.3
      Definition reproduced here.

      A method is signature polymorphic if all of the following are true:
      • It is declared in the java.lang.invoke.MethodHandle class or the java.lang.invoke.VarHandle class.
      • It has a single variable arity parameter (§8.4.1) whose declared type is Object[].
      • It is native.
      Returns:
      true if the method has Polymorphic Signature
