Themes: Prevent a Full Site Editing theme from being activated when Gutenberg is not active.

Browse Source 
When a theme that uses the Full Site Editing feature is activated and the Gutenberg plugin is not present, the site will currently show a text notice on the front end. The user is not made aware of this unless they visit the front end of their site.

This adds a check that will prevent a theme from being activated when the `full-site-editing` tag is present in the theme’s `style.css` header and the Gutenberg plugin is not active to prevent this scenario.

These checks can be removed once Full Site Editing is completely merged into Core.
