gpu: nvgpu: unit: add negative tests for common.gr.obj_ctx

Browse Source 
Add negative tests that inject memory allocation failures and
HAL function call errors to verify error handling path in
common.gr.obj_ctx unit.

Update common.gr.setup test to cover invalid class input while
setting preemption mode.
