Support media query in SCSS preload link

[Sir-Will]

Hi,

it would be great if we can use the media query in the preload feature. For example:

--woltlab-suite-preload:	#{preload(
                                '../images/custom/header_large.jpg',
                                $as: "image",
                                $crossorigin: false,
                                $type: "image/jpg",
                                $media: "(min-width: #{$wcfLayoutMaxWidth + 1px})",
