[css-fonts] Clarify font-display descriptor value names

[jetvillegas]

An issue is noted in the spec re: the allowed values for font-display:
https://drafts.csswg.org/css-fonts-4/#issue-01b739ba

Blink has shipped with the names per spec. Gecko plans to do the same. Strike the spec issue as resolved? /cc: @tabatkins

[litherum]

Why don't we resolve the issue once Gecko ships, to give people time to comment?

[jetvillegas]

We could do that, though our ability to change syntax is greatly reduced once multiple browsers ship.
