vp9-rtc: Extract content dependency in cyclic refresh For usage in the external RC. When content_mode = 0, the cyclic refresh has no dependency on the content (motion, spatial variance, motion vectors, etc,). The content_mode = 0, when compared to content_mode = 1, on rtc set for speed 7: has some regression on some clips (~3-5%), but overall/average bdrate loss is about ~1-2%. Comparing aq_mode=3 with content_mode = 0, vs aq_mode=3: about ~14% avg/overall bdrate gain, but has ~3-7% regression on some hard motion clip (e.g.m street).
