Add ApplicationInfo.isEncrpytionAware() as a system API.

applicationInfo.isDirectBootAware() ||
applicationInfo.isPartiallyDirectBootAware() was used by Settings
to determine whether to show a confirmation message for setting a
direct boot unaware app to be some default app (e.g. SMS). Since
we are moving default app into roles in PermissionController, we
need this as a system API.
