Introduce Split operation into pureACL runtime (#2447)

* Introduce Split operation into pureACL runtime

This commit introduces Split operation into pureACL runtime.

Signed-off-by: Jiyoung Yun <jy910.yun@samsung.com>
* Remove num_split_index of Split operator

The `num_split_index` is always the same with the number of output.
So it can be omitted.
