[Autofill] Use LocationBarBubbleDelegateView enum as reason ...

... in AutofillBubbleHandler.

Before this patch:
Each bubble used to call the enum value using its own class name.
(specifically SaveCardBubbleViews and LocalCardMigrationBubbleViews)

After this patch:
LocationBarBubbleDelegateView is used instead when referring to
USER_GESTURE and AUTOMATIC enum values.
