rtc: Alllow source_sad selectively for speed >= 10
Enable source_sad speed feature for speed >= 10,
but only selectively based on the current frame
avg_source_sad (running average) and the current QP.
The source_sad is used to condition the increase
in partition thresholds and usage of modeled_nonrd_cost.
Enabling it locally gets ~4% bdrate gain on desktop_ex2,
and ~2% on several other clips, and some clips have no change.
avg bdrate gain ~0.5% on rtc set, with --cdf-update-mode=2.
Speed slowdown measured on vga clips is ~2%.
