Subject: [PATCH] rtc-screen: Remove speed feature for speed 11

For speed 11 screen content mode: remove the speed
feature setting of zeromv_skip_based_on_source_sad,
(keep it same as in speed 10). This significantly
reduces visual artifacts observed in issue below.

Across the rtc_screen set:
~0.4% bdrate loss, ~3% IC slowdown.
