gpu: nvgpu: remove use of NVGPU_CTXSW_FILTER_ISSET

Browse Source 
- Remove the usage of NVGPU_CTXSW_FILTER_ISSET splattered
across nvgpu, and replace with a MACRO defined in common code.
The usage is still inside Linux, but this helps the
subsequent unification efforts, e.g. to unify the fecs trace
path.
- Remove "uapi/linux/nvgpu.h" from common code.
