Separate animations and add dragOffSet points in dragOptions

For 1, when animateShift() is called shiftAnimation() is the only thing needed.
2, by having point saved in preDragCondition, we can use that to update the drag layers and not have to
modify registrationX/Y later

Removed dragVisualizedOffset since it does not do anything.

There is an issue that also needs to be fixed if user decides to long click
on a search result and let go, the icon flashes at the touch point when you let go.. so we check when mContent can be shown in DragView
depending on if there is dragOffset.
If there is dragOffset, set mContent to invisible.
If there is no dragOffset, set mContent to visible because it doesn't matter as the original content is at the same spot.
