Update to variance partition. Use force_split to constrain the partition selection. This is used because in the top-down approach to variance partition, a block size may be selected even though one of its subblocks may have high variance. In this patch the selection of the 64x64 block size will only be allowed if the variance of all the 32x32 subblocks are also below the threshold. Stil testing, but some visual improvement for areas near slow moving boundary can be seen. Metrics for RTC set increase by about ~0.5%. Change-Id: Iab3e7b19bf70f534236f7a43fd873895a2bb261d
