Add framework to compute distance in display order

This patch adds framework for av1_encoder_get_relative_dist()
which will compare the absolute display order hint to compute
the relative distance and overcomes the limitation of
get_relative_dist() which returns incorrect distance when
very old frame is used as a reference.
