Specialization of AAModelIsSupported for MODEL == AAModelStl, yielding true_type if TYPE::allocator_type exists; otherwise, yielding false_type unless AAModelIsSupported<TYPE, AAModelBsl> is true. The latter condition exists so that bsl‐AA always implies stl‐AA even if AAModelIsSupported<TYPE, AAModelBsl> is explicitly specialized to true for a type that does not have an allocator_type member.
