Refer to C23 in place of C2X in glibc

Browse Source 
WG14 decided to use the name C23 as the informal name of the next
revision of the C standard (notwithstanding the publication date in
2024).  Update references to C2X in glibc to use the C23 name.

This is intended to update everything *except* where it involves
renaming files (the changes involving renaming tests are intended to
be done separately).  In the case of the _ISOC2X_SOURCE feature test
macro - the only user-visible interface involved - support for that
macro is kept for backwards compatibility, while adding
_ISOC23_SOURCE.

Tested for x86_64.

@ -14,6 +14,13 @@ Major new features:
in order to support unsigned __int128 and/or unsigned _BitInt(N) operands
with arbitrary precisions when supported by the target.
* The GNU C Library now supports a feature test macro _ISOC23_SOURCE to
enable features from the ISO C23 standard. Only some features from
this standard are supported by the GNU C Library. The older name
_ISOC2X_SOURCE is still supported. Features from C23 are also enabled
by _GNU_SOURCE, or by compiling with the GCC options -std=c23,
-std=gnu23, -std=c2x or -std=gnu2x.
