conform: Add initial support for C23.

Browse Source 
Hi Joseph,

As we discussed, this patch just makes C23 include every check that is
performed by C11.

I tested the commit by adding the ISO23 Make and Python variables to be
the same as ISO11.  So the only difference was compiling with -DISO23
instead of -DISO11.  And changed the temporary directories to instead
use the format f'/tmp/glibc-{self.standard}-{self.header}'.  Then I used
a shell script to run 'cmp' on each file in the ISO11 and ISO23
directories for each header to make sure they were the same.

Make C23 checks include every test that is performed by C11.  Done by
running the following command:

find conform -name '*.h-data' | xargs sed -i \
  -e 's| !defined ISO11| !defined ISO11 \&\& !defined ISO23|g' \
  -e 's| defined ISO11| defined ISO11 \|\| defined ISO23|g' \
  -e 's|ifdef ISO11|if defined ISO11 \|\| defined ISO23|g' \
  -e 's|ifndef ISO11|if !defined ISO11 \&\& !defined ISO23|g'
