DLP: Show a notification instead of a toast for blocked printing.

According to the latest mocks we need to show a notification instead
of a toast when printing is blocked due to Data Leak Prevention
configuration.
See mocks: https://docs.google.com/presentation/d/1v0GM-lwHCznFJ6hnZlUH37eBOuAkJMw5Q6UnSkcKOgA/edit?hl=en#slide=id.ga3a0b63111_0_321
