Confirmed PyRefTracer_DESTROY not being sent (with GIL enabled (non-debug build)) when ceval deallocs objects, this fixes it. I don't know of a current method to add a regression test in python (will address in a separate PR).

See: #130696

tracemalloc is a no for the test so added to _testcapimodule. Didn't reuse _simpletracer because that stores a limited number of object pointers and I figure its useful to be able to count an arbitrary number of reftraces. Let me know if keep this or move test location or remove.

Sorry, @tom-pytel and @colesbury, I could not cleanly backport this to 3.13 due to a conflict.
