Inject blocks.css styles as editor styles as well

This is an attempt to fix https://github.com/Automattic/wp-calypso/issues/54990. 

Please note that we added the file as-is, without much consideration to the rest of CSS and the clashes that might occur. 

This PR is intended to show a quick way to fix the issue.
