Bug 5050963: Suggestion popup moves with its associated TextView

Generalisation of the onPreDraw listener pattern for all popup windows
(SuggestionsPopupWindow, ActionPopupWindow and HandleView).

Added a shared PositionListener class that tracks movements of the
parent's TextView and limit calls to hierarchy to get this position from
different places.
