drm/amdkfd: enable cooperative groups for gfx11
MES can concurrently schedule queues on the device that require exclusive device access if marked exclusively_scheduled without the requirement of GWS. Similar to the F32 HWS, MES will manage quality of service for these queues. Use this for cooperative groups since cooperative groups are device occupancy limited. Since some GFX11 devices can only be debugged with partial CUs, do not allow the debugging of cooperative groups on these devices as the CU occupancy limit will change on attach. In addition, zero initialize the MES add queue submission vector for MES initialization tests as we do not want these to be cooperative dispatches.
