X Title: gh-99113: Share the GIL via PyInterpreterState.ceval.gil by ericsnowcurrently · Pull Request #104203 · python/cpython

Description: In preparation for a per-interpreter GIL, we add PyInterpreterState.ceval.gil, set it to the shared GIL for each interpreter, and use that rather than using _PyRuntime.ceval.gil directly. Note that _PyRuntime.ceval.gil is still the actual GIL. There is a <1% performance penalty. (This change is broken out from gh-99114.) Issue: gh-99113
