When LockPatternUtils#setLockCredential() fails, it can either return
false or throw an exception. Catch the exception and treat it the same
way as a false return value, to prevent crashing com.android.settings.
Bug: 253043065
Test: Tried setting lockscreen credential while in secure FRP mode using
smartlock setup activity launched by intent via adb. Verified
that com.android.settings no longer crashes due to the exception
from LockPatternUtils#setLockCredential().

So the new password can be saved per caller's request.
This will remove the additional step to ask the user
to enter the new credential again and thus simplifying
the UI flow.

* Extract common code of ChooseLockPassword.SaveAndFinishWorker and
ChooseLockPattern.SaveAndFinishWorker to the parent class.
* Make setters return this to make it easy to chain setter calls.
* Rename SaveChosenLockWorkerBase to SaveAndFinishWorker.
This will make the code changes in the next CL much easier.
