Summary [BlackBerry] Touch cancel can cause huge and needless invalidations

PR #198051 In order to remove the possible hover effect on touch_cancel, we always invalidate the node under the fat finger, being the fat finger valid or not. Point is having a valid fat finger node does not mean the original touch position was actually adjust for clicking or that the fat finger is actually valid. We set the fat finger node to be the result of the point-based hit-test regardless if it is a click target or not (in order to make our mouse-move machinery to work). We should can less aggressively invalidate the fat finger node, since it can be rather an expensive call (longer than 1s in the worst scenario).
