"system-ui" generic font family

CSS

This generic font family allows authors to style contents so it fits within the system UI.

Comments

Safari and Firefox shipped the old name, "-apple-system" on Mac, and has a bug to rename and support other platforms, but that has not been done yet. Blink has shipped non-standard name, "BlinkMacSystemFont" again only on Mac. This feature supports the standardized name on all platforms, includes aliasing old name on Mac and measure the usage for deprecation.
