Speed up keyframe encoding with model RD model_rd_for_sb() can quickly compute an approximated RD cost. We use the estimated RD cost to skip running full RD for some bad mode candidates. This only affects keyframe encoding. Observed 22% encoding time reduction, and 0.03% compression loss. Change-Id: I793f1eda98d67e8da9bc1648dcf272222b30a556
