Use ChooseLockGeneric When Started By Admin App

The device management app may run before the end of device provisioning,
and it may start SetNewPasswordActivity.  If this happens, use
ChooseLockGeneric instead of SetupChooseLockGeneric.  Only use
SetupChoseLockGeneric if SetNewPasswordActivity was started by Setup
Wizard itself.

Fixes: 151552453
Test: atest com.android.settings.password.SetNewPasswordActivityTest
Test: atest com.android.settings.password.ChooseLockGenericTest
Test: Manually run consumer and enterprise device setup
