Subject: [PATCH] Block Editor: Load the classic layout stylesheet
 conditionallty.

Historically, the block editor has been opinionated about the size of the canvas and the alignments.
Themes with theme.json will have to define a "layout" in their settings and the classic stylesheet won't be loaded anymore for this.

Props nosolosw.
See #53175.
