drm/amdkfd: add multi-process debugging support for GC v9.4.3

Similar to GC v9.4.2, GC v9.4.3 should use the 5-Dword extended
MAP_PROCESS packet to support multi-process debugging.  Update the
mutli-process debug support list so that the KFD updates the runlist
on debug mode setting and that it allocates enough GTT memory during
KFD device initialization.
