Enable more precise background detection for partition decision This commit compares the current original frame to the previous original frame at 64x64 block level and decides if the entire block belongs to background area. If it is in the background area, skip non-RD partition search and copy the partition types of the collocated block in the previous frame. For vidyo1 in the rtc set, this makes the speed -5 coding speed about 8% faster. The overall compression performance is down by 1.37% for rtc set. Change-Id: Iccf920562fcc88f21d377fb6a44c547c8689b7ea
