This can apply to optional, nullable parameters of platform types. This will cause the generator to generate the type as `Optional` rather than `JS::GCPtr`, allowing the implementation to differentiate between...

In order to do so, we need to define animation composite ordering as well as some other misc helper methods. Work towards #21570

As the title suggests, these commits implement the final behavior required before we can fully transition `StyleComputer` to Web Animations. Work towards #21570

This PR fixes all but one issue seen in the demo I posted in [this comment](https://github.com/SerenityOS/serenity/pull/23311#issuecomment-1961601978). Here is a new demo: https://github.com/SerenityOS/serenity/assets/28801118/3ab9bb12-78d0-4bcf-9dff-ab1d45be1366

I did this for the creation of the key frame set in `KeyframeEffect` for Web Animations, but forgot to do it in `StyleComputer` for `@keyframes` rules. Fixes #23367

With this PR, we can interpolate between transforms whose functions don't match. For example: `translate(100px)` -> `scale(2) translateX(50px)`. New video of the demo: https://github.com/SerenityOS/serenity/assets/28801118/fa1079af-50cd-43f0-b0ad-a2b80c21a376 (I'm assuming the GPU painter doesn't...

Consider the following snippet: ```html div { --some-var: -100px; animation: anim 1s infinite; } @keyframes anim { to { transform: translateX(calc(var(--some-var) * -1)); } } hello world ``` Before #23622,...
