servo: Merge #17364 - Implement paint worklet properties (from asajeffrey:script-paint-worklets-properties); r=jdm <!-- 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. --- <!-- Thank you for contributing to Servo!

Bug 1380092 Return 0 instead of nullptr r=jld nullptr is explicitly not allowed to be cast to an int. But uintptr_t is an unsigned int that happens to be large enough to hold a pointer. Return 0, which is an int. MozReview-Commit-ID: 2SE76JuJLCo
