    [IA] Move optional button to LocationBar

    - Create an OptionalButtonCoordinator in LocationBarCoordinator for
      phones only.
    - Add logic to show/hide new optional button dynamically.
    - Update ToolbarPhone to proxy calls into LocationBar except on the
      NTP. On the NTP the identity disk is still presented in the optional
      button. Will refactor post-launch.
