RTC: Remove rate control's dependency on sad_based_comp_prune

Currently, realtime mode's rate control relies on the array
src_sad_blk_64x64, which is only allocated/populated when the
sad_baed_comp_prune speed feature is enabled. This causes some
discrepancy in rate control at different speed settings. This commit
removes the dependency so that src_sad_blk_64x64 is always populated.
