gpu: nvgpu: add test type for boundary values checks in SWUTs

-Allow only usermode submit, check for gpfifo max size.
-Map buffer offset must be page aligned and in multiple of page size.
-Check for unmapped address whether it's alloced or not.
-Offset in alloc space must be multiple of page size.
-Free space offset must be in the range of alloced space.
