[rAC, OSX] saveInChrome status now persistent.

The AutofillDialogController already persisted the state of the
"Save in Chrome" checkbox. This CL ensures that the OSX dialog reflects
that persisted state and is properly updated when the state changes.

This is a re-land of r226376, with fixed tests.
