Make empty entries list respect user permissions

[wiegertschouten]

Currently, an empty collection index always looks like this:

This is regardless of the current user's permissions.

I think the following would be ideal:

• Configure Collection should only be visible for users with the configure collections permission.
• Configure Blueprints should only be visible for users with the configure fields permission.
• Scaffold Views should only be visible for super users, because they are generally the only ones for whom this is relevant.

I'll try and submit a PR when I find the time 🤞🏻

For reference: I think this should work the same way as the show view: https://github.com/statamic/cms/blob/0d98e11db6b24980235468f772222f75ebd875b7/resources/views/collections/show.blade.php#L33-L59
