Summary [HDR] Disable HDR display for CSS images

Reported 2025-02-19 11:18:15 PST
Currently only the headroom of HTMLImageElements are checked for setting the GraphicsLayer::drawsHDRContent(). So a layer with an HDR <img> element, has to show the CSS HDR image the same way if is displayed in a layer with no HDR <img> element. For now and to be consistent with HDR CSS images, the HDR display will be disabled for CSS images.
