2/n: Add BiometricPrompt implicit UI

In small mode, tapping the gray are is ignored. Combined
StatusBar#showBiometricTryAgain into onBiometricAuthenticated(bool)

We now create a new BiometricDialogView object for each BiometricPrompt
authenticate call. This makes the view's lifecycle much easier to manage.

Bug: 111461540

Test: Small -> Big when error or rejected
Test: Small -> Authenticated looks good
Test: Try again button is shown when rejected
Test: Icon spacing looks good after animation
Test: Big/small state persists across configuration change
