Updating fast scrollbar UI in Landscape

Creating a separate view for FastScrollBar and moving all the relavant logic in
the view.
For protrait, the touch handling is delegated by the recycler view just like before.
For landscape, the dcrollbar does not overlay with recyclerView and handles the touch
itself
