Remove comments column for Media list view

[knutsp]

In case empty( get_option('wp_attachment_pages_enabled') ) remove the then unnecessary 'comments' column.

This is a follow-up to #57913.

PR for Trac ticket: https://core.trac.wordpress.org/ticket/64201

This PR removes the “Comments” column from the Media Library when attachment pages are disabled.

When the wp_attachment_pages_enabled option is empty or evaluates to false, attachments no longer have dedicated front-end pages. In such cases, displaying the “Comments” column in the Media Library becomes redundant, since comments are not accessible or visible on attachment pages.

#### Benefits:

• Prevents confusion for users by hiding irrelevant UI

• Keeps the Media Library interface cleaner

• Aligns with the expected behaviour when attachment pages are disabled
