Vincent Fazio 76cd14167f package/python3: bump python to 3.12.4 
Along with the version bump, a number of the patches have been dropped
or reworked.

Compiled shared module builds are now disabled via py_cv_module_* = n/a
when possible (see PY_STDLIB_MOD_SET_NA). Leveraging this method allows
dropping numerous patches.

Note: this method does not work when access to a compiled module is
wrapped by a python-based module such as sqlite, tkinter, etc. In these
cases, configure knobs are still required to disable these modules and
their wrappers.

Both setup.py and distutils are no longer utilized upstream, so patches
have been dropped or adjusted accordingly.

Patch 0007 has been dropped, the Xtensa architecture can avoid compile
errors by using a toolchain with kernel headers newer than 3.17 [0].
That would require a new, non-trivial dependency to be added, but it
would also need to be propagated to all packages that select python3; as
we consider xtensa with old headers to be a corner case, we decide to
not address the issue, and rather add an exclusion in genrandconfig to
avoid the issue in autobuilders.

Patch 0026 has been dropped, the issue is fixed in uClibc v1.0.37+ [1].
Note: uClibc is not generally supported by upstream CPython.

While we're making assumptions about uClibc, ac_cv_func_wcsftime=no is
no longer set as it was fixed in v1.0.0 [2].
