Update CUDA packages (attempt 2)

[ali-ramadhan]

The main point of upgrading is to get rid of CUDA errors on the CPU and use CUDAapi.has_cuda() which replaces the HAVE_CUDA variable we've been using.

This was originally in PR #378 (this PR is mostly cherry picked commits) but when it was merged @glwagner reported issues with forcing functions on the GPU.

So now I've added a test that makes sure that forcing functions don't crash when used in a CPU or GPU model (one with and one without const).

[glwagner]

ya.

Should also add some tests with sin and exp just to be complete? This will additionally test whether GPUifyLoops is correctly replacing these with their CUDAnative flavors.

I added three forcing function + time-stepping tests to make sure it always works now. CPU and GPU tests passed on Google Cloud so all CI pipelines should pass hopefully.

@glwagner Please approve and merge if it looks okay.

[glwagner]

Thanks for updating the example too.
