accessibility: Add pointer accessibility support

Browse Source 
Adds the UI part for the pointer accessibility features.

The various timeouts running are notified using a pie-timer showing
under the pointer.

For dwell-click type selection, we use a drop-down menu. Users can
use the dwell-click to select the next type of dwell click to be
emitted.
