This is a placeholder issue for when the spec of the layout options is finalized.

Note that ideally, this layout panel will be integrated with the existing one where needed. Since this is currently not possible in Gutenberg, hacky solutions like CSS hiding are allowed as per this comment (pdnLyh-30z-p2#comment-1948).

Whether settings should be duplicated in the toolbar and inspector controls, or only implemented in the inspector controls it's still a decision to be made.
