impl ToResolvedValue for Content

https://drafts.csswg.org/css-content/#content-property

We implement this at resolved value time because otherwise it causes us to allocate a bunch of useless initial structs for ::before / ::after, which is a bit unfortunate.

Though these should be temporary, mostly, so if this causes complexity in other places, it should be fine to move to StyleAdjuster.

See https://github.com/w3c/csswg-drafts/issues/4632 for where some related issues are being discussed.
