CSS env() support

[kanongil]

See w3c/csswg-drafts#1693.

Safari TP currently includes support for this. It is also supported on iOS 11.0 using the previous constant() syntax.

iOS 11.1 uses the current env() syntax.

. . . Beginning with Safari Technology Preview 41 and the iOS 11.2 beta, constant() has been removed and replaced with env().
