Improve global motion estimation
Description
This merge request replaces the custom global error metric with the sum of the absolute differences as mentioned in #2141. These changes came from @rachelbarker_at_google. I just backported them to SVT-AV1 from libaom. No cleanup is performed in this merge request. Only very basic testing with obj1-fast was performed, to ensure the videos encoded.
