Add PyUnicode_AsUTF8() function to the limited C API.
multiprocessing posixshmem now uses PyUnicode_AsUTF8() instead of
PyUnicode_AsUTF8AndSize(): the extension is built with the limited C
API. The function now raises an exception if the filename contains an
embedded null character instead of truncating silently the filename.
* PyUnicode_AsUTF8() now raises an exception if the string contains
embedded null characters.
* Update related C API tests (test_capi.test_unicode).
* type_new_set_doc() uses PyUnicode_AsUTF8AndSize() to silently
truncate doc containing null bytes.

There were a few things I did in gh-110565 that need to be fixed. I also forgot to add tests in that PR.
(Note that this PR exposes a refleak introduced by gh-110246. I'll take care of that separately.)
Fix detection of gdb built without Python scripting support.
* check_usable_gdb() doesn't check gdb exit code when calling
run_gdb().
* Use shutil.which() to get the path to the gdb program.
The PySys_Audit() function was added in Python 3.8 by the PEP 578
"Python Runtime Audit Hooks".
Add also PySys_AuditTuple() to the limited C API, function added
to Python 3.13.
Move non-limited "PerfMap" C API from Include/sysmodule.h to
Include/cpython/sysmodule.h.
Add PyMem_RawMalloc(), PyMem_RawCalloc(), PyMem_RawRealloc() and
PyMem_RawFree() to the limited C API.
These functions were added by Python 3.4 and are needed to port
stdlib extensions to the limited C API, like grp and pwd.

zipinfo now supports the full range of values in the TZ string
determined by RFC 8536 and detects all invalid formats.
Both Python and C implementations now raise exceptions of the same
type on invalid data.
Now re.error is raised instead of OverflowError or RuntimeError for
too large width of look-behind pattern.
The limit is increased to 2**32-1 (was 2**31-1).
* tty.setraw() and tty.setcbreak() previously returned partially modified
list of the original tty attributes. Now they return the correct list of
the original tty attributes
* tty.cfmakeraw() and tty.cfmakecbreak() now make a copy of the list of
special characters before modifying it.
It already mostly worked, except in the case when invalid keyword
argument with non-ASCII name was passed to function with non-ASCII
parameter names. Then it crashed in the debug mode.
Replace select.epoll() with selectors.DefaultSelector to support
FreeBSD 14 and newer.
* Merge common code between test_timerfd_epoll()
test_timerfd_ns_epoll().
* Replace "_ = func()" with "func()".
* Add TimerfdTests.read_count_signaled() method.
