Deprecate CC and add BP#buildIntent()

To ensure future BP builder changes don't require a 1:1 addition to the
CC API, we're deprecating CC and moving the API to BP.

Since CDC is an activity, and BP can't receive onActivityResult from CDC,
we need to have BiometricService launch CDC. CDC will return auth/reject
results to BiometricService using a private protected aidl method, which
can then forward the reuslt to BP/app.
