  ENH: Add a NpyAuxData c_metadata to PyArray_Descr

The purpose of this is to allow dtypes with metadata to
have faster C-level performance. With this, datetime64
metadata lookup can become a single C pointer dereference,
compared to a C-string to Python-string conversion +
a Python dict lookup as it is presently.
