Capture all settings used by layouts

Problem/Motivation

Some layouts, come with additional options that can be selected when adding sections in the Layout builder interface, but not in this module. For example, the layouts provided by core layout_builder allow a user to select the specific width of 2-3-4 columns layouts. Without the additional information provided by those fields, the proper classes are never added to the layout.

Steps to reproduce

1. Install layout_builder and this module
2. In a text format select a format that uses additional settings. There will be multiple options that say "Two column", but the one that has the machine name layout_twocol_section has the additional settings. A similar situation exists with "Three column" (layout_threecol_section).
3. If you add the layout in the "Layout" tab on a node, you'll see a "Column widths" field, but there is no such field when adding the same layout with this module.

Proposed resolution

Add a field to capture the additional settings to render the appropriate markup.

Remaining tasks
