Description: This was discussed in #131969 (cc @ZeroIntensity), but deferred to get the smaller change in. This PR adds all of the core interpreter types currently exposed in the types module to _typesmodule.c. We then change the definition of types.py to prefer these, but if the _types module is not available, to use the pure-Python fallbacks. Strictly, this isn't needed, as _types is a built-in module. I think it might be helpful to keep the pure Python definitions for other implementations (PyPy, etc), and perhaps as a quick reminder of what each type looks like. Open to thoughts on this, as it would clearly be simpler to replace everything with from _types import *. I've initially categorised this under #118761, as this does provide a ~15% speed-up for me (1627µs to 1403µs). A Issue: gh-118761
