cabana: add filter per column (#28034)

* add non functional lineedits * implement actual filtering * more efficient modelReset * less diff * refactor contains * make sortMessages static * cleanup * regex support * case insensitive * uncomment * set header before restoring state * force reset * more regex matching * update comment * put back header with clear button * handle hiding * handle horizontal scrolling * whitespace * dont add that
