config: Enable Touch timer in SurfaceFlinger
When Touch timer is disabled in SF, Content Fps Detection algorithm
considers the layer as infrequent and switches to lower Refresh Rate,
for the frame at the beginning of the scrolling use cases. When layer
becomes frequent after few frames, then algorithm switches back to
peak refresh rate. This sequence of events leads to couple of Refresh
rate switches, which are unnecessary. On the other hand, when touch
timer is enabled, touch remains active and the algorithm picks-up the
peak refresh rate to boost the performance at the beginning of scroll
and then layer becomes frequent, so there is no refresh rate switch.
