Rewire BiometricEnrollActivity to setup pages

When running in setup flow:
- If fingerprint enrollment is desired, go to
  SetupFingerprintEnrollIntroduction
- Makes sure WizardManagerHelper.copyWizardManagerExtras is called
  to propagate the extras from the incoming intent, propagating
  extras like whether we are in initial / deferred setup flow, theme,
  etc.
- Forward the result code in BiometricEnrollActivity using
  FLAG_ACTIVITY_FORWARD_RESULT
