Mojo C++ bindings: support enum validation.

By default, enums are not extensible, which means any unknown value will fail validation. If an enum may grow in the future, it needs to have [Extensible=True] attribute specified. In that case, the user code is responsible for handling unknown values properly.

This CL doesn't add corresponding validation for JS or Java.
