In order to properly handle CSS clipping, we need to keep track of what
the different kinds of clips that we have. On one hand, clipping due to
overflow rules should respect the containing block hierarchy, while CSS
clipping should respect the flow tree hierarchy. In order to represent
the complexity of items that are scrolled via one clip/scroll frame and
clipped by another we keep track of that status with a
ClipAndScrollInfo.

The traversal currently expects every flow to have a scroll root id
assigned, even if it doesn't produce any display items. This change
fixes the error that arises from this situation.

<!-- Please describe your changes on the following line: -->
This PR speculatively calls paint worklets during style, which increases the concurrency, since it increases the chance that the cache will have the right result in it when it comes to layout. The speculation is wasted effort if the size of the element has changed, but this is often not the case.

DO NOT MERGE until https://github.com/servo/webrender/pull/1399 has landed in Servo.
Previously webrender was reserving 1MB of space for each display list (empirically pages weighed between 100k and 10MB when I implemented this). This was problematic for gecko because they used webrender differently. This just brings Servo back to where it was.

padding, which could lead to some content being clipped when it
shouldn't. This changes fixes that issue.

This is the final PR to get basic paint worklet support. It adds support for paint worklet properties (https://drafts.css-houdini.org/css-paint-api/#paint-definition-input-properties). When a paint worklet is registered, it specifies a list of CSS properties, and is provided with their computed values when it is invoked.
This is a dependent PR:
* "Implemented paint worklets invoking worklet scripts" is #17239.
* "Implemented paint worklets rendering contexts" is #17326.
There should be tests added for this, hopefully the existing wpt houdini tests.
