rtc: Updates/fixes for temporal layers

Increase the motion search for the base temporal (TL0)
layers (every 4 frames for 3 temporal layers). This
leads to quality increase with slowdown. To offset the
slowdown, for the non_reference_frames (TL2): increase
the base partition threshold and adjust motion search
parameter (use prune_more and max step_size).
Add rt speed flag to directly set/control the step_param
in nonrd_pickmode.

For 3 temporal layers at speed 7: avg. bdrate gains of
~2% on rtc set (max 8%), with ~3% slowdown.
