Refer to C23 in place of C2X in glibc
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.

in order to support unsigned __int128 and/or unsigned _BitInt(N) operands

* 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
