rtc: Fine tune sf skip_intra_pred_if_tx_skip

For better speed quality trade-off, this CL adds a new
conservative level as level 1 in skip_intra_pred_if_tx_skip
speed feature and the existing level is mapped to level 2.
This change improves the quality of speed 7 and also enables
the sf for speed 8 at level 1 for speed 9 at level 1 and 2
for rtc_derf and rtc respectively.
