SF: use TextureView hint when selecting the refresh rate
SF would only try to heuristically calculate the frame rate of a layer
when TextureView is updating. This fixes a bug where SF tries to
heuristically calculate the frame rate for UI animations but fails
due to long frames.
Bug: 280249265
Test: Playing a video on Facebook and observe refresh rate
Test: go/cb-pcmark
