seat: add missing touch_frame handler

Browse source 
wl_touch::frame() is expected to be sent to client to indicate end of
touch frame event and not sending it may cause issues.
For example, Qt applications using Qt Wayland platform plugin do not
consider touch events until this end of frame to be received.
