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.

Remove asserts that confuse enum _framestate

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
a53cc3f49463e50cb3e2b839b3a82e6bf7f73fee (GH-116687). Remove the incorrect
checks for `owner != FRAME_CLEARED` as well.
