Manually routing Accessibility clicks for RecyclerView classes.

DocsUI uses TouchDetector to differentiate mouse/gesture events; this
prevents a11y services to know what logic to run when there's a
ACCESSIBILITY_CLICK event. This CL manually adds these accessibility
click events to child views, and also route these to correct click
callbacks.
