12/n: Add LockPatternView for setDeviceCredentialAllowed(true)

Includes lock icon, title, subtitle, description, lock pattern view.
Corner radius and padding animates nicely from !=0 --> 0.

Support for password/pin will come in a subsequent CL.
Unit tests for AuthCredentialView will be added when
password/pin are implemented.

Support for persisting across configuration changes
and landscape view will also be added in a subsequent
change.

Test: BiometricPromptDemo with the following:
      1) Confirm pattern, callback received
      2) Rejected, error string shown
      3) Lockout (5 attempts), countdown string shown,
         pattern view disabled until countdown is over
      4) Cancel pattern auth, callback received
Test: atest BiometricServiceTest
Test: atest com.android.systemui.biometrics
