rtc: Allow for compound modes for nonrd_pickmode

For nonrd mode (speed >= 7): add LAST_GOLDEN compound
average mode for 0_0/NEAREST_NEAREST/NEAR_NEAR,

avg. bdrate gain rtc set: ~5.3/5/3.5% for speed 7/8/9.
avg. bdrate gain rtc_derf: ~0.5% for speed 7.

Speed slowdown of ~10-15% on 360p/480p clips.

Keep the speed feature (use_comp_ref_nonrd) off for now
(it's already off as default).
