In Fonts 4, there are several new CSS generics available for font-family:

* system-ui (see bug 1226042)
* emoji
* math
* fangsong

system-ui is implemented in both Safari and Chrome, AFAICT (Edge not yet tested); we should do it for parity. (Note that we currently have -apple-system, but on macOS only.)

The emoji generic would be useful to allow sites to ask for the system's default emoji font rather than listing all the emoji fonts they happen to know about. This would offer a better way forward for cases like bug 1460445.
