This class (and the rest of the patch) seems like this is the first place where
we're starting to bridge the gap between EmbeddedWorkers and ServiceWorkers -
meaning that EmbeddedWorkers as an abstraction have been mostly clean and
ignorant of ServiceWorker specifics. I had been previously wondering if we
should break out embedded worker stuff into its own directory (i.e.
content/browser/embedded_worker etc)

I'm fine with what you're doing here, but maybe we can have a refactoring down
the line, and in the mean time we can start naming things (like messages) with
the EmbeddedWorker name, so that refactoring is more obvious for whoever ends up
doing it.
