SurfaceFlinger: Add touch events to Scheduler
Add the notion of Touch Events to Scheduler to enhance the algorithm
to move to Performance refresh rate.
Scheduler selects Performance when:
- There is a touch event
- There is a buffer to HWC
This change also removes the behavior of Scheduler to move to Performance
on Choreographer callbacks.
Test: Switch between apps using gesture navigation
