[3.12] GH-107263: Increase C stack limit for most functions, except `_PyEval_EvalFrameDefault()` (GH-107535) (#107618)
GH-107263: Increase C stack limit for most functions, except `_PyEval_EvalFrameDefault()` (GH-107535)
* Set C recursion limit to 1500, set cost of eval loop to 2 frames, and compiler mutliply to 2.
