gpu: nvgpu: load context image from gr/ctx unit

Browse Source 
We currently load and create new graphics context image in
gr_gk20a_load_golden_ctx_image()
This API will first load local golden image in new context
image and then initialize context appropriately by calling
g->ops.gr.ctxsw_prog() HALs

Move this sequence to gr/ctx unit and rename the API as
nvgpu_gr_ctx_load_golden_ctx_image()

Note that call to g->ops.gr.update_ctxsw_preemption_mode()
is moved out of this API and called directly from
gk20a_alloc_obj_ctx()
