Make `PyCodeObject._co_unique_id` conditional on `Py_GIL_DISABLED`
Feature or enhancement
Proposal:
PyCodeObject._co_unique_id is currently declared unconditionally, but its usage is entirely in free-threaded code paths. So maybe we can make _co_unique_id only present when Py_GIL_DISABLED is enabled.
Has this already been discussed elsewhere?
