[patch] libgomp.texi: Update OpenMP 6.0-preview implementation-status list

This commit updates the OpenMP 6.0 implementation status,
https://gcc.gnu.org/onlinedocs/libgomp/OpenMP-Implementation-Status.html

Besides some reordering and adding a bunch of 'N' entries, it also adds
'Y' for the recent C23 attribute changes.

Comments? If not, I will commit it later...

Tobias

PS: I am sure the wording can be improved; suggestions welcome, but,
nonetheless, I should do for an implementation list.
