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.
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.
End TreeBuilder's reliance on DOM.

This is a patch that unifies a bit how Gecko and Stylo stylesheets work, in
order to be able to eventually move the stylesheets into the stylist, and be
able to incrementally update the invalidation map.
Deduplicating code is nice, and it will help us when we make the bit
propagation more complicated in upcoming patches.

WR multi-document update
<!-- Please describe your changes on the following line: -->
The PR updates WR version to support multiple documents (https://github.com/servo/webrender/pull/1509) but doesn't take advantage of this new feature yet.
It also makes Servo to use `DevicePixel` from WR instead of rolling out another one.

The alias is left there temporarilly and will be removed completely in a later commit where
also components/style/gecko/generated/structs_{debug|release}.rs are re-generated (they still
use the old alias).
Suppress CSS parser errors for vendor-prefixed properties.
This matches the behaviour of Gecko's CSS parser.

This allows us to have ensure_data() and clear_data() functions on the TElement
trait, instead of hacking around it adding methods in random traits.
This also allows us to do some further cleanup, which I'd rather do in a
followup.
This reverts commit ebfc8f5858, reversing
changes made to 5585ff2c44.
Animation code can reenter and create a new TLS context from the traversal
SequentialTask, so this won't work as written.
Removed unused import
Removed unused import `script_layout_interface::reporter::CSSErrorReporter in components/layout_thread/lib.rs
