(JSC::JSFunction::getOwnPropertySlot):
Add a new GeneratorWrapperMethodMode parse mode. The other function types
(async, arrow) already have a FunctionMode and a MethodMode. Give
generators one as well. This lets isMethodParseMode actually be accurate.

Extend to cover method duplicate parameter cases.
