Indexing ndarray should give empty array output

[reminisce]

Description

When indexing an ndarray with an index greater than the dim size, it should produce an empty ndarray as in NumPy, instead of throwing an error.

>>> import mxnet as mx
>>> mx.npx.set_np()
>>> a = mx.np.arange(1)
>>> a
array([0.])
>>> a[1:]  # index exceeds dim size, should result in an empty array instead of throwing an error
