[csswg-drafts] [css-fonts] Suggest allowing a list of font-family values in @font-face (#3691)

faceless2 has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-fonts] Suggest allowing a list of font-family values in @font-face ==
@font-face only allows a single value for the "font-family" entry, but I can't think of a reason that a list shouldn't be allowed here, and at times it could be useful.

An example: "NotoSans-Black.ttf" has two names in the OpenType name table: "Noto Sans" and "Noto Sans Blk". While best practice would be to define the Noto sans families like so:
```
@font-face {
    font-family: "Noto Sans";
    font-weight: 900;
    url(NotoSans-Black.ttf);
}
@font-face {
    font-family: "Noto Sans";
    font-weight: 400;
    url(NotoSans.ttf);
}
```
I can't think of any ambiguity that would arise if you could also do this:
```
@font-face {
    font-family: "Noto Sans", "Noto Sans Blk";
    font-weight: 900;
    url(NotoSans-Black.ttf);
}
@font-face {
    font-family: "Noto Sans";
    font-weight: 400;
    url(NotoSans.ttf);
}
```
This would be also useful if the font has names in several languages, eg "MS Mincho" and "ＭＳ 明朝". In fact that's probably a more compelling usecase, I should have opened with that really.

Finally, it's also an advantage when generating @font-face rules automatically from font files; there's no need to choose which of the several names an OpenType font is known by as the definitive one, you can just list all the appropriate entries.
