Browser Plugin: Use asynchronous input events

Currently, if the guest is unresponsive, we kill the guest and return control back to the embedder.

This approach switches to asynchronous input events. The guest always swallows input events.

This CL also introduces 'unresponsive' and 'responsive' events.
