The clip for overflow:scroll clip was not including the space for
padding, which could lead to some content being clipped when it
shouldn't. This changes fixes that issue.
A test is skipped because this fix also stops hiding a failure due to
mispositioned text.
Fixes#16576.
Implement paint worklet properties
<!-- Please describe your changes on the following line: -->
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.

Implement the InputEvent
Add WebIDL, from UI Events working draft.
Implement script type for event.
Note that actually firing InputEvents is not part of this commit.
<!-- Please describe your changes on the following line: -->
As part of my effort to improve [keyboard handling](https://groups.google.com/forum/#!topic/mozilla.dev.servo/e6R7eBDjo4M) it is necessary to introduce the InputEvent. While I have a working prototype using the input event this still needs a lot of work before it can be merged into servo.

Propagate changes in custom properties' computed values to descendants
If ComputedValues.custom_properties differs between the old and new
ComputedValues, indicate that we have to propogate changes to
descendants by setting child_cascade_requirement to
MustCascadeDescendants in cascade_primary.
style::matching::TElement::cascade_primary already calls
accumulate_damage, which eventually calls
ServoRestyleDamage::compute_style_difference in order to check if other
properties' computed values changed. If any of those change, we signal
that we need to propogate changes for inherited properties.
With Properties & Values, some custom properties will not be inherited,
and we will need to revisit this.

The pref `webgl.testing.context_creation_error` will cause creation of a new WebGLRenderingContext to fail, iff set to true.
Also update test expectation of `context_creation_error.html` to pass.

Don't optimize display list for projective transforms
There are situations where elements are transformed from outside the
display list. With projective transforms it's currently difficult to
detect these. In those cases we just don't optimize the display list,
so that they will always be shown.
Fixes#13822.
