Adding Legal Message to Migration Dialogs

1) Added legal message (clickable) to the offer dialog.

2) Added a Close Button which will be shown when the
user clicks save button and the migration process lasts for more than
5 secs.

3) Modified ChromeAutofillClient to enable passing legal message
to the LocalCardMigrationDialogControllerImpl.

4) Adjusted format/style of the dialog contents according to the mock:
go/autofill-paradise.

5) Added an experiment flag (disabled by default) to control whether we want to show migration
feedback to the user.
