Send callingUserId from AuthService -> BiometricServiceBase

Since authenticatorIds are collected from AuthService, which is
system_server, we need to get the callingUserId before the code
enters system_server, which clears calling identity.

Test: 1) Set up work profile, install BiometricPromptDemo
      2) Enroll work profile fingerprint
      3) Open work profile version of BiometricPromptDemo
      4) Create biometric-bound keys and authenticate with fingerprint
      Before this change, key was unusable. After this change,
      the key can be used
