backend-rdp: implement set_dpms

Browse source 
set_dpms() is used for sleep/wakeup. output_repaint_timer_handler() resets the
repaint_status if called while Weston is sleeping. If the timer is still active,
it will trigger a call to weston_output_finish_frame() which then triggers an
assertion, because the repaint_status is not REPAINT_AWAITING_COMPLETION.
Stop the timer and reset the repaint_status in this case to avoid this.

Schedule a repaint for WESTON_DPMS_ON to ensure that the current state is
rendered.
