mad.m: Improve compatibility using new mean/median functions (patch #10331) */scripts/statistics/mad.m: Add 'omitnan' option to mean and median function calls to enable ignoring NaN input values. Add empty input handling shortcut codepath. Update docstring to describe new behavior and options 'all' and vecdim. Add BISTs for added/updated features. Remove dim input validation BISTs now handled by mean and median. */etc/NEWS.9.md: Add entry describing mad.m changes under Matlab Compatibility section.
