I agree with esprehn that getBlob() / getFile() is a poor name for factories. We
usually use createXXX() format. We don't expose this to JS so I don't think we
really need to be consistent with the naming of BlobBuilder (Could not find a
corresponding BlobBuilder.idl).

Done.
I renamed get{Blob, File} to create{Blob, File}.

BlobBuilder was a thing a few years ago. Then it was deprecated in favor of the
Blob constructor. I think this is why the IDL is gone, but the class still
exists.

I still think the whole class needs to go into platform/blob, or its
functionality should be completely assimilated into BlobData.

Follow-up refactoring maybe?

Right, there's no reason to keep this class any more. We should be able to clean
up BlobBuilder and code around it.
