[AF Android] Creating Dropdown Refresh Impl

This CL:
* Adds a boolean parameter to AutofillDropdownAdapter to allow us to
  programmatically choose between two visual styles (the existing UI,
  and the WIP visual refresh).
* Removes dividers drawn between items in the refresh case.
* Wires up the existing feature and flag which will control which style
  is used.
