- Adds the notice "This page is always wide" and disables the inputs for the "width" options in the Appearance menu when pages are excluded via configuration ( `$wgVectorMaxWidthOptions`). - Changes layout behaviour so that pages in the $wgVectorMaxWidthOptions['exlcude'] configuration stretch the entire viewport width. - Stops the width settings in the Appearance menu from being hidden on smaller resolutions. Bug: T364015 Change-Id: Idee294adf3b309e03834276ea75e4ae43b0cffcb
