Add TouchVideoDevice

TouchVideoDevice will represent a video device that reports heatmaps.
The heatmaps are strength of the signal at each point of the
touchscreen, taken at a particular time.

The only purpose of TouchVideoDevice is to read TouchVideoFrames.

Test: this is a partial cherry-pick of a standalone binary that was used
to pull heatmaps. Integration tested by observing the action of
InputClassifier HAL.
