This adds a macro `Py_CAN_START_THREADS` that corresponds to the Python
function `test.support.threading_helper.can_start_thread()`. WASI and
some Emscripten builds do not have a working pthread implementation.
This macro is used to guard the critical sections C API tests that
require a working threads implementation.
The random module now imports the _sha2 module lazily in the
Random.seed() method for str, bytes and bytearray seeds. It also
imports lazily the warnings module in the _randbelow() method for
classes without getrandbits(). Lazy import makes Python startup
faster and reduces the number of imported modules at startup.
In PGO mode, this function caused a compiler error in MSVC.
It turns out that optimizing for space only save the day, and is even faster.
However, without PGO, this is neither necessary nor slower.
In most cases, doctest is not needed. So don't always import it at
startup. The change reduces the number of modules already
imported when a test is run.
Drop posix.fallocate() under WASI.
The underlying POSIX function, posix_fallocate(), was found to vary too
much between implementations to remain in WASI. As such, while it was
available in WASI preview1, it's been dropped in preview2.
Critical sections are helpers to replace the global interpreter lock
with finer grained locking. They provide similar guarantees to the GIL
and avoid the deadlock risk that plain locking involves. Critical
sections are implicitly ended whenever the GIL would be released. They
are resumed when the GIL would be acquired. Nested critical sections
behave as if the sections were interleaved.

I added _Py_excinfo to the internal API (and added its functions in Python/errors.c) in gh-111530 (9322ce9). Since then I've had a nagging sense that I should have added the type and functions in its own PR. While I do plan on using _Py_excinfo outside crossinterp.c very soon (see gh-111572/gh-111573), I'd still feel more comfortable if the _Py_excinfo stuff went in as its own PR. Hence, here we are.
(FWIW, I may combine that with gh-111572, which I may, in turn, combine with gh-111573. We'll see.)
