Extend early_term_luma_palette_size_search sf to speed 0

Extended the speed feature early_term_luma_palette_size_search to
speed 0 with a less aggressive header rdcost based breakout
condition for speed 0 path. Existing sf=1 logic is now moved under
sf=2 path. Also, the name of the speed feature is changed to
prune_luma_palette_size_search_level to indicate the level of
aggressiveness of pruning.
