gpu: nvgpu: don't build sw semas for dgpu

Browse Source 
Make tu104's sema cmd HAL ops depend on CONFIG_NVGPU_SW_SEMAPHORE
in addition to the kernel mode submit flag.

Drop CONFIG_NVGPU_SW_SEMAPHORE from NVGPU_FORCE_DGPU_SAFETY_PROFILE.
Semaphore-based synchronization is not actually needed for dgpu.
