Ralf W. Grosse-Kunstleve a5665e3aca fix: type_caster_enum_type for pointer types (#5694 ) (#5776 )

Add pointer overload to type_caster_enum_type::cast method to handle
enum pointer casting. Fixes compilation error when returning pointers
to enum types from bound functions.

Experiment for validation:

Temporarily undo the changes in include/pybind11/cast.h:
