This PR adds a new mypyc primitive for `weakref.ref` I wasn't able to figure out what name mypyc expects for `weakref.proxy`, so I took that out and will keep that for a separate PR later on. ref is more commonly used than proxy anyway. for later, I tried: - weakref.proxy - weakref.ProxyType - weakref.weakproxy no luck with those also for later, I'll need to finish #19145 to add a primitive for `weakref.ref.__call__`

We need a new C function because of the variability of PyWeakref_GetRef

Is this still WIP? |

Ah no, this one is ready for review. Though I wouldn't call it "complete" quite yet. One open question, I'll add a comment in the code |

I think there's gotta be a better place for this, but I wasn't able to figure out how to make function_op or method_op work with the __call__ method
