[Sync] [Mac] Implement one-click signin bubble for OS X
Add new class OneClickSigninBubbleController.
Factor out logic from views implementation of one-click bubble so that
both it and OneClickSigninBubbleController can behave similarly.
BUG=117899,116685
TEST=On OSX, with a clean profile, sign into GMail. The one-click infobar should pop up, clicking "OK, sync" should bring up the one-click dialog, and confirming should bring up the bubble by the wrench menu.
