[csswg-drafts] [css-sizing] Restrict 'stretch' and 'fit-content' to width/height and max-*

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

== [css-sizing] Restrict 'stretch' and 'fit-content' to width/height and max-* ==
The definitions of `stretch` and `fit-content`/`fit-content()` don't seem to make any sense for the `min-*` properties, or at least have extremely minimal use-cases (we can't think of any) and so aren't worth the effort of impl/testing.

We've gone ahead and removed them from the propdefs, just need WG approval for it.
