Auto merge of #15356 - servo:font-face-descriptors, r=Manishearth

Add support for more @font-face descriptors

<!-- Please describe your changes on the following line: -->

Part of https://bugzilla.mozilla.org/show_bug.cgi?id=1290237. I’ll add conversions to `nsCSSValue` separately because that requires new C++ functions in the stylo repository.
