bpo-47196: Fix function pointer cast in test_imp (GH-32244)
The function PyInit_imp_dummy is declared as void f(PyObject* spec)
but called as void f(void). On wasm targets without the call
trampolines this causes a fatal error.

API. The _PyFrameEvalFunction callback function type now uses the
_PyInterpreterFrame type which is part of the internal C API.

bpo-47146: Stop Depending On regen-deepfreeze For regen-global-objects (gh-32218)
This effectively reverts the Makefile change in gh-31637. I've added some notes so it is more clear what is going on.
We also update the "Check if generated files are up to date" job to run "make regen-deepfreeze" to ensure "make regen-global-objects" catches deepfreeze.c.
bpo-45847: Port _tkinter to PY_STDLIB_MOD (GH-31698)
- Remove ``--with-tclk-*`` options from `configure`
- Use pkg-config to detect `_tkinter` dependencies (Tcl/Tk, X11)
- Manual override via environment variables `TCLTK_CFLAGS` and `TCLTK_LIBS`
Add _PyCFunctionObject_CAST() and _PyCMethodObject_CAST() macros to
make macros casting their argument easier to read, but also to check
the type of their input in debug mode: assert(PyCFunction_Check(func)
and assert(PyCMethod_Check(func).
Reformat also PyCFunction_XXX() macros for readability.
Add macros to cast objects to PyASCIIObject*, PyCompactUnicodeObject*
and PyUnicodeObject*: _PyASCIIObject_CAST(),
_PyCompactUnicodeObject_CAST() and _PyUnicodeObject_CAST(). Using
these new macros make the code more readable and check their argument
with: assert(PyUnicode_Check(op)).
Remove redundant assert(PyUnicode_Check(op)) in macros using directly
or indirectly these new CAST macros.

bpo-35859: Fix a few long-standing bugs in re engine (GH-12427)
In rare cases, capturing group could get wrong result.
Regular expression engines in Perl and Java have similar bugs.
The new behavior now matches the behavior of more modern
RE engines: in the regex module and in PHP, Ruby and Node.js.
The enter_context is updated with following information: 'The :meth:`__enter__` method
returns the ExitStack instance, and performs no additional operations.'

Shared extension on Emscripten now have suffix
``.cpython-311-wasm32-emscripten.so`` (JS loader) and
``.cpython-311-wasm32-emscripten.wasm`` (WebAssembly code).
The goal here is to reduce potential confusion between
`assert_type(val, type)` and `assert isinstance(val, typ)`.
The former is meant to ask a type checker to confirm a fact, the latter
is meant to tell a type checker a fact. The behaviour of the latter more
closely resembles what I'd expect from the prior phrasing of
"assert [something] to the type checker".

bpo-46712: Do not Regen Deep-Frozen Modules before Generating Global Objects (gh-32061)
We have to run "make regen-deepfreeze" before running Tools/scripts/generate-global-objects.py; otherwise we will miss any changes to global objects in deep-frozen modules (which aren't committed in the repo). However, building $(PYTHON_FOR_FREEZE) fails if one of its source files had a global object (e.g. via _Py_ID(...)) added or removed, without generate-global-objects.py running first. So "make regen-global-objects" would sometimes fail.
We solve this by running generate-global-objects.py before *and* after "make regen-deepfreeze". To speed things up and cut down on noise, we also avoid updating the global objects files if there are no changes to them.
