Use whether we've computed any viewport unit instead.
This is more accurate (we avoid restyling unnecessarily if we've found anything
ever on the stylesheet, but that hasn't matched).
This has the benefit of also matching Gecko, and simplify some code and
fishyness around, and also hopefully speeding up stylesheet parsing.
stylo: Implement font feature values lookup
This PR reviewed by emilio and xidorn on bugzilla. That is backed out because of Windows build problems. Fixed and landing it again.

Devirtualize CSS error reporting.
This removes a trait object from the path of reporting a CSS error.

style: Move the StyleSheetSet into the Stylist.
This will allow tracking whether there have been only additions to the
stylesheet set, and in that case don't destroy and completely rebuild the
invalidation map.
This is on top of #18143.

This will allow tracking whether there have been only additions to the
stylesheet set, and in that case don't destroy and completely rebuild the
invalidation map.
This is a temporary step needed to support Gecko's getKeyframes() API
until we implement bug 1391537. It only takes effect when
a ComputedValues object is supplied and only for longhand declarations.
The only reason why we had the `existing_style_for_style_damage` bit is to apply
some optimizations that we don't have anymore.
I still want to reintroduce a few of them, at least for the non-eager
pseudo-element case... But I think I won't need this at all.
This allows us to remove a fair amount of Gecko code too.
This moves us to clear on rebuild, which allows us to remove yet another place
where we track stylist dirtiness.

Bindgen bitfield enums don't work as return values with the Linux 32-bit ABI at
the moment because they wrap the value in a struct.
This causes the Rust side to believe the callee expects space for the struct
return value, while C++ believes it's just an integer value.
