Add support for passing policies to the allow_subclass method in embind. This allows the use of constructors that require policies, such as those taking raw pointers, when enabling C++ subclassing from JavaScript. Previously, allow_subclass only accepted a constructor argument, making it impossible to use policies like allow_raw_pointer with the generated 'implement' method.
