[Fingerprint] Add fingerprint enroll in setup wizard

Make a subclass for each enrolling screen that setup wizard uses, and
in override the corresponding get*Intent methods to always use the
setup wizard versions of the next screens.

On minor change made to the original flow is that it will now return
RESULT_OK if it is finished, as opposed to RESULT_CANCELED.
