Scrollbar gutter component

This provides an API and adds a --scrollbar-gutter custom property to the <html> element with the detected thickness of the scrollbar, which is updated lazily on viewport resize. This is based on a technique by David Walsh, as demonstrated in this JSFiddle. Once the scrollbar-gutter CSS property is supported in all major browsers, this component may become unnecessary.
