Automatic update from web-platform-tests
Revert "Generate canvas layer global state tests with new test variants feature."

This reverts commit 446ce8aea96e6d4696d9702c1ac86861c9c8cdf6.

Reason for revert: causes failures on mac11-arm64-rel-tests e.g.

https://ci.chromium.org/p/chromium/builders/ci/mac11-arm64-rel-tests/13707

Original change's description:
> Generate canvas layer global state tests with new test variants feature.
>
> All of these tests were very similar with the only important different
> being the global state applied in the setup. Adding a "variant" feature
> to the test generation script allows for cutting a lot of this
> repetitive code.
