Code Review
This pull request introduces several cleanups and refactorings that improve the codebase. Moving CanvasKitVariant to a more central location, abstracting resourceCacheMaxBytes to the base Renderer class, and simplifying the ICU data injection logic are all positive changes. The optimizations in OcclusionMap are also a welcome improvement.
I have one main point of feedback regarding the implementation of resourceCacheMaxBytes for the Skwasm renderer, which appears to be incomplete. Please see the specific comment for details.

I think the Skwasm renderer should support setResourceCacheMaxBytes.

- `injectClientICUIfNeeded` as a method on `SkParagraphBuilder` for convenience. - Move `CanvasKitVariant` outside of `canvaskit/` because it's needed outside of that folder. - Make `resourceCacheMaxBytes` a method on all renderers, not only CanvasKit. - Some optimizations in `OcclusionMap`. - Remove unused CanvasKit test utils.
