[SPARK-9360] [SQL] Support BinaryType in PrefixComparators for UnsafeExternalSort
The current implementation of UnsafeExternalSort uses NoOpPrefixComparator for binary-typed data.
So, we need to add BinaryPrefixComparator in PrefixComparators.
Author: Takeshi YAMAMURO <linguin.m.s@gmail.com>
Closes #7676 from maropu/BinaryTypePrefixComparator and squashes the following commits:
