Document -Wc11-c2x-compat.
My patch that added initial C2X support and associated command-line
options missed documenting -Wc11-c2x-compat although the other options
were properly documented. This patch adds the missing documentation.
Tested with "make info" and "make pdf".
* doc/invoke.texi (-Wc11-c2x-compat): Document.
