Refactor test: Enable generality in testing UOp alu expressions (#10200)

Browse Source 
* use function for infinity instead of uniform

* test infinity math locally

* test infinity math in CI

* make pytest available to MacOS (WebGPU)

* revert to master except failing webgpu test

* isolate test refactor
