HtmlLayoutFilesExtensions.LayoutCssFiles method

Renders stylesheet links for all the CSS files declared with LayoutCssFileAttribute and resolved by ILayoutCssFileProvider, so that dynamically loaded libraries can contribute layout styles without a page specific entry point. When CSS bundling is enabled (Enabled), the files are concatenated into one dynamic CSS bundle served from ~/DynJS.axd/; otherwise a link is rendered for each file. Returns an empty string if there are no files, or if the result was already included in this context.
