drm_hwcomposer: Add property hwc.drm.primary_display_order

There are cases when primary display lookup order should be
overriden. This could be achieved with adding system property
hwc.drm.primary_display_order.

Example of primary_display_order property usage:
hwc.drm.primary_display_order=HDMI-A-2,HDMI-A-1,...

This means that first priority goes to HDMI-A-2 connector, then
HDMI-A-1 connector, then everything else. Internal connectors have
higher priority than any other connectors not mentioned in property.

Connected connector with highest priority would be selected as a
primary display.
