SF: Temporarily expose primary display id
WM needs to know the address of the primary display in order to
consume ro.surface_flinger.primary_display_orientation correctly.
This path will be removed in the future once we support per
display install orientations.
Bug: 196167822
Test: check initial buffer transforms on displays with a different
install orientation
