ClimaComms.@elapsed not working correctly on CUDADevice

[Sbozzolo]

Unfortunately, it looks like that ClimaComms.@elapsed is not using CUDA.@elapsed. See, for example, https://buildkite.com/clima/climaatmos-ci/builds/19101#018fea6e-9626-4c61-a653-3d72a751a817

Ah, there is a typo here :

ClimaComms.jl/src/devices.jl

Line 182 in ae67a34

$(__CC__).cuda_elasped($expr)

(Looks internally consistent, however)

Bummer, can we move this issue to ClimaComms? We should probably add tests for this. Maybe we can inspect the macroexpanded code and make sure that CUDA’s sync is exists.

the other macros very well may be broken, too.
