[META] Layout builder editorial improvements

Added ✨ Provide a way to opt-out of inline blocks in layout builder based on context Needs work as I think it fits the purpose of this epic.

I started moving some things around in the issue summary to group them based on the challenge that we are trying to solve.

I get asked "Why can't I just place and edit this field in layout mode? Why do I have to switch tabs?".

Being able to work with individual entity fields entirely from layout builder would be a considerable improvement. The edit tab could be optional.

Related to that is ✨ Use layout builder for content add/edit form Active

@John Pitcairn when we use Layout builder, we only put the title (And maybe some meta fields) on the node-type. Everything else is in block-types that map to components in the design system.

We also redirect from node create (which is just adding a title) to the Layout tab

And in some cases we auto add a hero component based on the title.

We use entity editor tabs module to rename the tabs to 'Edit metadata' (normal edit form) and 'Edit content' which is LB.

Sure, but that places a considerable restriction on the entity architecture, right? For example, you get to jump through additional hoops to make a simple view of entities if the entity no longer has fields - not much fun as a site builder.

Right, we limit to landing pages. We might have a title, 'teaser text' and 'teaser image' field on just the 'edit metadata' tab, and use those for listing pages.

Ah. Ideally I'd want this on any public-facing "page" but with restrictions on how the layout can be modified per entity bundle - so it's a very consistent wysiwyg editorial experience, in the front end theme. But with Drupal's strong storage architecture, linked to components, and neither a body field junk pile or deeply nested entity relationships. Ha.

Should this be added to the Meta? 🐛 Olivero: Media library within Layout Builder modal is unstyled Needs work or some what to use media library without needing a dozen templates?
