[Autofill Sync] Adding option to dropdown

This CL adds a new option to the Autofill dropdown footer. This consists
of:

* Changes to components/autofill to include the row as a suggestion
  under the appropriate conditions.

* Changes to the native popup views to display properly if only footer
  rows are present. (This was not possible before the introduction of
  the new row type.)

* Updates to the autofill_popup_layout_model to return a Google "G" logo
  as one of the possible icons.

* Moves a Google "G" logo vector icon to be available on platforms other
  than Mac.

Updating the priority, I assume it was just left on the default? :)

Verified in Canary; requesting merge.

This CL addresses UI and privacy/disclosure concerns for Sync Transport for Autofill Payments. Some of these concerns were raised quite recently thanks to feedback received during and after the DICE launch.
