vp9: Increase thr_var for 32x32 blocks in var-based partitioning.
For real-time mode, increase variance threshold for 32x32 blocks in var-based partitioning for resolution >= 720p, so that it is more likely to stay at 32x32 for high resolution which accelerates the encoding speed with little/no PSNR drop. PSNR effect on different speed settings: speed 8 rtc: 0.02 overall PSNR drop, 0.285% SSIM drop speed 7 rtc: 0.196% overall PSNR increase, 0.066% SSIM increase speed 5 rtc_derf: no effect. Speed up: gips_motion_WHD, 1mbps: 2.5% faster on speed 7, 2.6% faster on speed8 gips_stat_WHD, 1mbps: 4.6% faster on speed 7, 5.6% faster on speed8 Change-Id: Ie7c33c4d2dd7d09294917e031357fc5476c3a4bb
