C++ pointers to Carbon methods are supported using the same mechanisms as for Carbon functions: we export the method to C++ and then form a pointer to the exported method. This change does not support invoking a C++ method pointer from Carbon, which will be more complicated because we need to model instance binding on the Carbon side.
