gh-129668: Fix thread-safety of MemoryError freelist in free threaded build (gh-129704) 
The MemoryError freelist was not thread-safe in the free threaded build.
Use a mutex to protect accesses to the freelist. Unlike other freelists,
the MemoryError freelist is not performance sensitive.

Implement PyUnicode_KIND() and PyUnicode_DATA() as function, in
addition to the macros with the same names. The macros rely on C bit
fields which have compiler-specific layout.

gh-112075: Remove critical section in dict.get (gh-129336) 
The `dict.get` implementation uses `_Py_dict_lookup_threadsafe`, which is
thread-safe, so we remove the critical section from the argument clinic.

Add a test for concurrent dict get and set operations.

gh-128844: Make _Py_TryIncref public as an unstable API. (#128926) 
This exposes `_Py_TryIncref` as `PyUnstable_TryIncref()` and the helper
function `_PyObject_SetMaybeWeakref` as `PyUnstable_EnableTryIncRef`.

These are helpers for dealing with unowned references in a safe way,
particularly in the free threading build.

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.
