Subject: [PATCH] PowerManagerService: notify SurfaceFlinger on power hint

To reduce jank on the first buffer, SurfaceFlinger needs to know when there is a touch
event so it can move to performance refresh rate before the first buffer

Test: switch between apps using gesture navigation
Bug: 131906818
