Add HPy<type>_Check for all fast equivalent type checks in CPython.

[fangerer]

There are some very fast Py<type>_Check functions in CPython that just do masking on the type flags (see https://github.com/python/cpython/blob/d460c8ec52716a37080d31fdc0f673edcc98bee8/Include/object.h#L433). HPy has a hard time to compete with that if we don't have dedicated functions that can be mapped to those in CPython ABI mode. We could still have a slightly different API that would then internally use those functions. OTOH, the migration path would be easier if we just introduce similar type checking functions.
