Implement high refresh rate policy in window manager

If an app is blacklisted or using the camera, we should switch
back to the refresh rate that is >= 60hz.

However, if the app is animating, we want it to be running at
90hz so we switch immediately when a window is animating or
about to animate.

Test: HighRefreshRateBlacklistTest
Test: RefreshRatePolicyTest
Test: manually added blacklist entry and checked refresh rate
Test: Verify that animations still run at 90hz
