rtc: Fix to color artifacts for real-time mode

Change the thresholds for setting the color_sensitivity
at superblock and coding block level, based on the
source_sad. Avoid screen-content for now.

Also, change the setting for estimating motion for
variance partitioning from 3 to 2 locally based
on superblock sad. Level 3 uses neighbor MVs without
using coarse motion estimation, and will early exit
based on source_sad. Forcing level 2 is safer for now.

This significantly removes artifacts on strong color
test clip.

Overall small and acceptable change in stats across
the rtc test sets.
