sdm: hwc2: Add support for HDMI as primary.

- Create external display if HDMI is already
  connected on boot.
- Wait for hotplug connect event if HDMI is not
  connected on boot.
- Notify surfaceflinger only once when primary
  display is created for first time.
- Destroy and recreate SDM external display on
  successive disconnect/connect. Do not notify
  surfaceflinger any subsequent hotplug events.
- Add null display implementation to route any
  incoming calls from surfaceflinger when display
  is disconnected.
