Fix up AutoFill profile editor UI in portrait mode

Create layout-port version of the autofill profile editor that extends
vertically rather than horizontally.

In both portrait and landscape, make the "Save profile" button
always visible, remove the "cancel" button as there are already several
ways to leave the activity without saving changes and move the "Delete
profile" button to the options menu.
