Using windowId from A11yWindowInfo instead

AccessibilityManagerService#getWindowBounds would return null if
using the windowId comes from the embedded hierarchy, and
EventDispatch#computeClickLocation will return CLICK_LOCATION_NONE
and can't perform long-click action. The fix try to use
AccessibilityWindowInfo's windowId to get correct window token to
get window bounds.
