event-rewrite: Clean up how events are rewritten.

Notable changes:
 * Make the EventRewriter a MessagePumpObserver. This is necessary to make sure
   that the event-rewrite happens before the event is dispatched.
 * Move the EventRewriter in chrome/browser/chromeos (and in chromeos namespace),
   since it does nothing on other platforms.
 * Get rid of the event-rewrite code from ash, since it just adds an extra layer
   of abstraction for no added value.

Added ability to override the number of retries after a browser crash

Set retry count for WebGL conformance tests to zero, because the likelyhood
of flaky crashes being significant are far higher for those tests.
