[OPPRO-266] Use the smaller table to build hashmap in shuffled hash join

[rui-mo]

What changes were proposed in this pull request?

Removed Spark's limitation for the build side of left and right outer join in shuffled hash join, so we could use the smaller table to build the hashmap. That means, LeftOuter and LeftSemi join can build left, and RightOuter join can build right when the left or right table is smaller.

How was this patch tested?

Verified on Jenkins.
