gpu: nvgpu: gv11b: enable more gr exceptions

-pd, scc, ds, ssync, mme and sked exceptions are
 enabled. This will be useful for debugging
-Handle enabled interrupts
-Add gr ops to handle ssync hww. For legacy
 chips, ssync hww_esr register is gpcs_ppcs_ssync_hww_esr.
 Since ssync hww is not enabled on legacy chips, added
 ssync hww exception handling for volta only.
