gpu: nvgpu: move local golden context memory allocation to poweorn

Browse Source 
- Separate out local golden context memory allocation from
  nvgpu_gr_global_ctx_init_local_golden_image() into a new function
  nvgpu_gr_global_ctx_alloc_local_golden_image().
- Add a new member local_golden_image_copy to struct
  nvgpu_gr_obj_ctx_golden_image to store copy used for context
  verification.
- Allocate local golden context memory from nvgpu_gr_obj_ctx_init()
  which is called during poweron path.
- Remove memory allocation from nvgpu_gr_obj_ctx_save_golden_ctx().
- Disable test test_gr_obj_ctx_error_injection since it needs rework
  to accomodate the new changes.
- Fix below tests to allocate local golden context memory :
  test_gr_global_ctx_local_ctx_error_injection
  test_gr_setup_alloc_obj_ctx
