error: identifier "CudaExec" is undefined

Hello everyone,

ascent_execution_policies.hpp only defines the struct CudaExec if Raja is enabled (ASCENT_RAJA_ENABLED).
But ascent_dispatch.hpp requires CudaExec if CUDA is enabled (ASCENT_CUDA_ENABLED) which is independent of Raja.

This results in the build error:

Hi @jhgoebbert

Thanks for this report and pointing to the root cause -- we had another build failure / symptom that I think was caused by this issue.

We will get this resolved.
