MDL-75386 theme: Include CSS from editor subplugins in editor style

Browse Source 
Editor stylesheets are kept separately to standard plugin stylesheets so
that they can be provided to style individual iframes where loading the
standard Moodle stylesheets would be incorrect.

Unfortunately the editor stylesheet system does not consider that
subplugins may want to add small individual styling to the editor but
this is required in some situations.
