SurfaceFlinger: record layer history for TX with eAnimation

If a transaction is posted with ISurfaceComposer::eAnimation flag,
record it with layer history. Layers with eAnimation are considered
animating and will vote for peak refresh rate.

Bug: 157695685
Test: Play 24fps video in YouTube PIP mode with setFrameRate and rotate the device - no jank
Test: Chrome playing video - no refresh rate switching
Test: Hide/Show keyboard when inputting text
Test: Running Hay Day and observing refresh rate
