gpu: nvgpu: use API to get golden image size

Browse Source 
Use API nvgpu_gr_obj_ctx_get/set_golden_image_size() exposed by
gr.obj_ctx unit to get/set size of golden image

Call nvgpu_gr_obj_ctx_init() from vgpu_gr_init_gr_setup_sw() to
initialize golden image size in gr.obj_ctx unit even on vGPU

Move g->ops.gr.falcon.init_ctx_state() call early in
vgpu_gr_init_gr_setup_sw() so that gr.ctx_vars struct is prepared
before fields in it accessed during rest of GR initialization
