Re: [csswg-drafts] [css-fonts] extend font-size-adjust to take a pair of values: <metric> <number> (#6160)

Suggested initial list: `ex`, `cap`, `ic`, `ch`. (With `ex` being the implied default, of course.)

I'm a little concerned about adding `ascent` or `extent`; a number of fonts have excess ascent to leave space for diacritics and stuff, and that extra space is a substantial proportion of the ascent of other fonts that cut the metric right at the Latin typographic ascent. So you'll get crazy results, depending on the fallback stack. (See slide 23 in https://fantasai.inkedblade.net/style/talks/vertical-rhythm/slides.pdf for an illustration.)
