ci: run cuda kernel tests

[ariostas]

In #3543 I missed testing the cuda kernel tests that are generated.

@ianna some of the tests-cuda-kernels-explicit tests are failing. Do you know if this is expected?

No, they all used to pass ... I'll have a look. Thanks!

I thought that maybe not installing pytest-xdist would fix things since @ikrommyd also reported unexpected failures in #3459, but it didn't fix it.

No no, xdist existing is fine since it's not being used. I wasn't getting any unexpected errors without xdist on my RTX 4080

@ariostas - this looks great! Please, merge it when you are done with it. Thanks!

Thanks for fixing it, @ianna!
