Philip Elcan 82ce44d882 gpu: nvgpu: unit: atomics: add cmpxchg threaded test ...

Add a threaded test for nvgpu_cmpxchg API. This test implements an
atomic increment using cmpxchg. It uses the existing arithmetic
threaded framework to use the cmpxchg_inc() function to verify 100
parallel threads increment the atomic the correct number of times.

These are L1 tests since they have longer run times and are unlikely to
regress.
