Print Preview Componentization: Add listeners for failed and presets

Add listeners for the print-failed and print-preset-options Web UI
events in the new UI, and migrate the behaviors of calling
onPrintFailed_() for print-failed and setting the copies and duplex
setting values based on the presets when they are received.

Also migrate the tests used to verify that presets work.
