ARROW-10968: [Rust][DataFusion] Don't build hash table for right side of join

This PR changes to not build an index for the probe side of the join. As I observed while writing the PR for adding an optimization pass for the build/probe side of joins, currently it takes more time to have the biggest table on the probe side, which is not what's expected.
The current implementation also creates a hashset for both the left and right side for each new batch for inner joins.

This change has big impact on join performance, e.g. TCP-H query 12 has a >4x speedup and query 5 a 16x speed up.

Query 12 (locally, in memory).
