Support multiple Enrollment APKs

Previously, the KeyphraseEnrollmentInfo would iterate through the list
of Enrollment APKs and just use the first one for a list of supported
keywords (of which there only could be one). Now, all APKs will be
enumerated and the enrollment APK that provides the given
keyphrase/locale will be used for the enrollment intent.
