c: Refer more consistently to C23 not C2X

Browse source 
Continuing the move to refer to C23 in place of C2X throughout the
source tree, update documentation, diagnostics, comments, variable and
function names, etc., to use the C23 name.

Testsuite updates are left for a future patch, except for testcases
that test diagnostics that previously mentioned C2X (but in those
testcases, sometimes other comments are updated, not just the
diagnostic expectations).

Bootstrapped with no regressions for x86_64-pc-linux-gnu.
