rtc: Tune force_large_partition_blocks sf to speed 8

Introduced new levels for the sf: force_large_partition_blocks
to act conservatively for speed 8 for variance based
partitions.
* Changed the name of sf to prefer_large_partition_blocks to
accomodate speeds other than speed 9.
* Refactored code to introduce a new function
tune_thresh_based_on_qindex_window()
