Safety build does not support vidmem. This patch compiles out vidmem related changes - vidmem, dma alloc, cbc/acr/pmu alloc based on vidmem and corresponding tests like pramin, page allocator & gmmu_map_unmap_vidmem.. As vidmem is applicable only in case of DGPUs the code is compiled out using CONFIG_NVGPU_DGPU.
