    Editor: Skip auto-attaching media when attachment pages are enabled.

    The block editor attaches unattached images in Image and Gallery blocks to the post when the post is saved. When attachment pages are enabled, attaching an image moves its attachment page to a URL under that post, and
    the old attachment page URL then returns a 404.

    This adds an `autoAttachMediaEnabled` setting to `get_default_block_editor_settings()`. It is `false` when the `wp_attachment_pages_enabled` option is on, and `true` otherwise. Sites can still change it with the
    `block_editor_settings_all` filter.
