[DO NOT MERGE]Fix AuthCredentialPatternView#onErrorTimeoutFinish() bug

1. When user auth fail on pattern view many times, the pattern view
   would be locked and disabled and wait for 30s timeout.
   Once timeout finish invoke, re-enabled pattern view is necessary.

2. Add AuthCredentialViewTest.java to extend PIN/Password/Pattern
   unit test coverage.

Bug: 243699695
Test: atest com.android.systemui.biometrics.AuthCredentialViewTest
Test: manual setup Pattern lock, try to wrong auth many times
      device locked for 30s patter view disabled
      once timeout, re-enabled pattern view
