[runtime] Throw exception for condition we don't handle in the dynamic registrar. (#20568)

Throw an exception for a condition we don't handle in the dynamic registrar:
calling a base Objective-C constructor (init method) with arguments. Our
current implementation to call the base Objective-C constructor doesn't handle
any arguments, so if the method actually takes any arguments, those will just
be random memory. In other words: a consistent exception is better than a
random invalid memory access.
