Missing GPU tests in the regular CAM regression test suite

[sjsprecious]

What is the feature/what would you like to discuss?

Currently all the CAM regression tests run on the Derecho's CPUs only. This will fail to capture any potential bugs that only break the GPU code (e.g., PUMAS) and any compiler bugs (mostly the NVIDIA compiler) related to the GPU code.

Is there anyone in particular you want to be part of this conversation?

No response

Will this change (regression test) answers?

No

Will you be implementing this enhancement yourself?

Yes, but I will need some help
