drm/amdgpu: pass queue size and is_aql_queue to MES
Update mes_v11_api_def.h add_queue API with is_aql_queue parameter. Also
re-use gds_size for the queue size (unused for KFD). MES requires the
queue size in order to compute the actual wptr offset within the queue
RB since it increases monotonically for AQL queues.
v2: Make is_aql_queue assign clearer
