rtc-svc: Modify speed feature for non-reference frames

For non-reference frames at speed >= 8:
-set subpel_search_method = SUBPEL_TREE_PRUNED_MORE
-enable disable_cdf_update_non_reference_frame
-set subpel reduction

And disable subpel reduction on base temporal layer.

This brings the speed-gap for 3TL AV1 vs VP9 closer
to the 1 layer speed-gap.

Stats changed
For speed 9 3TL (lm=2 pattern with 55-20-25 rate split):
rtc-derf: ~0.8% loss, ~2% speedup
rtc: ~0.7% loss, ~2% speedup
