net/mlx5: Add IFC bits for general obj create param

Before this patch, the log_obj_range was defined inside
general_obj_in_cmd_hdr to support bulk allocation. However, we need to
modify/query one of the object in the bulk in later patch, so change
those fields to param bits for parameters specific for cmd header, and
add general_obj_create_param according to what was updated in spec.
We will also add general_obj_query_param for modify/query later.
