Reason for revert:
This broke our app. We do not understand why the breakage happened or
why browser_tests could not catch this yet. However, as our app do not
want this in M36, I'd revert this change without checking.

BUG=372163


Original issue's description:
> Pepper: Clean up ProgressEvent logic.
> 
> This simplifies NexeLoadManager, which is getting pretty big. This also removes
> an unused field from ProgressEvent, and adds a convenience function for posting
> a task to dispatch a progress event from the main thread, which is often
> necessary to ensure that progress events are posted to the DOM after other
> state changes.
