gh-128923: Use zero to indicate unassigned unique id (#128925) 
In the free threading build, the per thread reference counting uses a
unique id for some objects to index into the local reference count
table. Use 0 instead of -1 to indicate that the id is not assigned. This
avoids bugs where zero-initialized heap type objects look like they have
a unique id assigned.

* tracemalloc_realloc() and tracemalloc_free() no longer
  remove the trace on reentrant call.
* _PyTraceMalloc_Stop() unregisters _PyTraceMalloc_TraceRef().
* _PyTraceMalloc_GetTraces() sets the reentrant flag.
* tracemalloc_clear_traces_unlocked() sets the reentrant flag.

Remove asserts that confuse enum _framestate with enum _frameowner (GH-124148) 
The `owner` field of `_PyInterpreterFrame` is supposed to be a member of
`enum _frameowner`, but `FRAME_CLEARED` is a member of `enum _framestate`.

At present, it happens that `FRAME_CLEARED` is not numerically equal to any
member of `enum _frameowner`, but that could change in the future. The code
that incorrectly assigned `owner = FRAME_CLEARED` was deleted in commit
a53cc3f494 (GH-116687). Remove the incorrect
checks for `owner != FRAME_CLEARED` as well.
