ContentOnly Write Mode: enable as a capability / role assignment

[annezazu]

In testing #65204 with various folks at WCUS, the topic of having this option enabled as part of a user role or capability came up. Adding this as an enhancement request for feature thinking. As an example, an agency creates a site and then could hand this off to a client to just update content rather than touch anything with design. cc @aaronjorbin & @mattreport who were two of the people who brought this up.

To what role would this cap be true by default?

[annezazu]

My two cents: I'd imagine it would be a capability not assigned to a role by default but that is available to be assigned when folks want to add it to a user role.

I would have to be available and enabled by dafault to roles so that editting can happen I suppose. I wonder if a corresponding Trac ticket would draw more attention here.

Just want to second that ideally this should be something we can control via either a user role or via a custom editor setting such as the canLockBlocks we already have.

On client sites there are some users we just want to be able to use the "Write" mode where as others should have the "Design" mode available.

Or if not completely block it at least having a way to change the default mode for certain user roles :)
