Disable the GIL by default in free-threaded builds #116329
Description
Feature or enhancement
Proposal:
Once #116167 is complete, users will be able to disable the GIL with PYTHON_GIL=0, but the GIL will remain enabled by default.
When we have enough confidence in the correctness of running without the GIL, we should change free-threaded builds to disable the GIL by default, as described in PEP 703.
This should be a very small code change, and is already detailed in this comment.
