Remove _PyInterpreterState_GetConfigCopy() and
_PyInterpreterState_SetConfig() private functions. PEP 741 "Python
Configuration C API" added a better public C API: PyConfig_Get() and
PyConfig_Set().
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_alloc(), tracemalloc_realloc(), tracemalloc_free(),
_PyTraceMalloc_TraceRef() and _PyTraceMalloc_GetMemory() now check
'tracemalloc_config.tracing' after calling TABLES_LOCK().
_PyTraceMalloc_TraceRef() now always returns 0.
* Use TABLES_LOCK() to protect 'tracemalloc_config.tracing'.
* Hold TABLES_LOCK() longer while accessing tables.
* 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.
Replaces the trampoline mechanism in Emscripten with an implementation that uses a
recently added feature of wasm-gc instead of JS type reflection, when that feature is
available.
Add free-threaded specialization for COMPARE_OP, and tests for COMPARE_OP specialization in general.

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.
Add a fast path to (single-mutex) critical section locking _iff_ the mutex
is already held by the currently active, top-most critical section of this
thread. This can matter a lot for indirectly recursive critical sections
without intervening critical sections.
I missed the extra `PyModule_Check` in #127660 because I was looking at
3.12 as the base implementation for import from. This meant that I
missed the `PyModuleCheck` introduced in #112661.
Methods (functions defined in class scope) are likely to be cleaned
up by the GC anyway.
Add a new code flag, `CO_METHOD`, that is set for functions defined
in a class scope. Use that when deciding to defer functions.
