Primitive descriptor query specification.

Rule of thumb: all opaque types and structures are returned by reference. All numbers are returned by value.
All returned references point to constant objects and are valid only during the lifetime of the queried primitive descriptor. Returned objects must not be destroyed by the user. If you need to keep the object longer than the lifetime of the queried primitive descriptor, use dnnl_primitive_desc_clone() to make a copy.
