drm/amd/display: Calculate scaling ratios on every medium/full update
[Why] If a plane isn't being actively enabled or disabled then DC won't always recalculate scaling rects and ratios for the primary plane. This results in only a partial or corrupted rect being displayed on the screen instead of scaling to fit the screen. [How] Add back the logic to recalculate the scaling rects into dc_commit_updates_for_stream since this is the expected place to do it in DC. This was previously removed a few years ago to fix an underscan issue but underscan is still functional now with this change - and it should be, since this is only updating to the latest plane state getting passed in.
