Support hiding post status and publish date controls in the post status panel

[costasovo]

What problem does this address?

Our team is using the block editor for editing email custom post types. Currently, we hide the post status panel in the sidebar (via removeEditorPanel( 'post-status' ); because it contains controls we don't want to present to the users.

The current state

For our usecase we would like to hide:

• status - we don't want to allow changing the status
• publish date
• word count, time read info - They don’t add much value in the email context

Desired state

We do want to add a couple of custom controls, ideally above the template option. Currently, it is possible to add new items only below the existing ones.

What is your proposed solution?

I don't know what would be the best solution here. I think we could add new options to the register_custom_post_type function to configure the post type to have a hidden status and publish date.

I think some of the cases are already covered in #61622. It might be a good idea to combine efforts there.

Yes, some block supports for this would be good. In addition to this. I think that whole sidebar should be refactored to be rendered using a DataForm and fields definition at some point (cc @oandregal) which means we should be able to offer another way to extend this using a declarative fields config or something.

I've created #76076 to track migration of the editor inspectors to use field-driven configuration (DataForm).

The "Time to read" line also doesn't always make sense for custom post types, so it would be great if it became opt-in for CPTs.
