Auto merge of #17364 - asajeffrey:script-paint-worklets-properties, r=jdm

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.
