Add an option (--enable-experimental-jit for configure-based builds
or --experimental-jit for PCbuild-based ones) to build an
*experimental* just-in-time compiler, based on copy-and-patch (https://fredrikbk.com/publications/copy-and-patch.pdf).
See Tools/jit/README.md for more information on how to install the required build-time tooling.
For interpreters that share state with the main interpreter, this points
to the same static memory structure. For interpreters with their own
obmalloc state, it is heap allocated. Add free_obmalloc_arenas() which
will free the obmalloc arenas and radix tree structures for interpreters
with their own obmalloc state.

The test_peg_generator test tried to link the python313_d.lib library,
which failed because the library is now named python313t_d.lib. The
underlying problem is that the "compiler" attribute was not set when
we call get_libraries() from distutils.
Make it possible for a converter to have multiple includes, by collecting
them in a list on the converter instance. This implies converter includes
are added during template generation, so we have to add them to the
clinic instance at the end of the template generation instead of in the
beginning.
Remove LibreSSL specific workaround ifdefs from `_ssl.c` and delete the non-version-specific `_ssl_data.h` file (relevant for OpenSSL < 1.1.1, which we no longer support per PEP 644).

This ensures the source directory is not modified at build time, and different builds (e.g. different versions or GIL vs no-GIL) do not have conflicts.
Rework error handling in the C preprocessor helper. Instead of monkey-
patching the cpp.Monitor.fail() method from within clinic.py, rewrite
cpp.py to use a subclass of the ClinicError exception. As a side-effect,
ClinicError is moved into Tools/clinic/libclinic/errors.py.
Yak-shaving in preparation for putting cpp.py into libclinic.
Move the following global helpers into libclinic:
- format_escape()
- normalize_snippet()
- wrap_declarations()
Also move strip_leading_and_trailing_blank_lines() and make it internal to libclinic.
Split up clinic.py by establishing libclinic as a support package for
Argument Clinic. Get rid of clinic.py globals by either making them
class members, or by putting them into libclinic.
- Move INCLUDE_COMMENT_COLUMN to BlockPrinter
- Move NO_VARARG to CLanguage
- Move formatting helpers to libclinic
- Move some constants to libclinic (and annotate them as Final)
Replace the internal accumulator APIs by using lists of strings and join().
Yak-shaving for separating out formatting code into a separate file.

* gh-65701: document that freeze doesn't work with framework builds on macOS
The framework install is inherently incompatible with freeze. Document
that that freeze doesn't work with framework builds and bail out
early when trying to run freeze anyway.

The 'version' directive was introduced with gh-63929 in Nov 2013. It has
not been in use in the CPython code base, and the 'version' variable has
never been bumped.
