Add shell command to set package

Adds an override to set the resume on reboot service provider. This
is needed to run CTS test with fake implementation. Note we won't
change the implementation provider once the resume on reboot flow
starts.

Bug: 178014912
Test: adb shell cmd lock_settings set-resume-on-reboot-provider-package com.android.cts.encryptionap;
      check the implementation is found correctly
