gpu: nvgpu: add gr/ctx API to init zcull in context

Browse Source 
gr_gk20a_init_golden_ctx_image() right now directly initializes
zcull state in context image by calling g->ops.gr.ctxsw_prog HAL

Add new API nvgpu_gr_ctx_init_zcull() in gr/ctx unit to do this
initialization and use it in gr_gk20a_init_golden_ctx_image()

Jira NVGPU-1527
