rtc: Fixes for temporal layers

Use better motion search for base temporal layer
TL0 (and also on TL1 for 3 temporal layers for now)
on speed 6 (this moves the logic up from speed 7).
And rate control fix to allow the QP to go down faster
after a key frame for temporal layers.

This improves performance: ~3-4% bdrate gain for sp 6
on rtc_set for 3TL (with lm=2), and reduces visual
artifacts observed after key frame.
