youknowriad 446dd1768a Block Editor: Add a type property to allow Core to identify the source of the editor styles.
Gutenberg plugin need to override the editor styles provided by core selectively,
this added property allows it to do so without committing to a public API.

Props nosolosw, jorgefilipecosta.
