ENH: Improved performance of PyArray_FromAny for sequences of array-like
Prior to this commit
np.array([array_like])
would recursively copy each element of array_like. This is due to the
fact that setArrayFromSequence only special-cased lists of NumPy arrays,
any other object was treated as a sequence even if it supported buffer
or __array*__ interfaces. See tensorflow/tensorflow#27692 for details.
The commit generalizes the special-case in setArrayFromSequence to any
array-like, i.e. a buffer or an object with __array__, __array_interface__
__array_struct__.
