Remove some Expr clones in `EliminateCrossJoin`(3%-5% faster planning)

[alamb]

~Draft as it builds on https://github.com/apache/datafusion/pull/10427~

Which issue does this PR close?

Part of https://github.com/apache/datafusion/issues/10287

Rationale for this change

I am trying to avoid copying as much in EliminateCrossJoin to speed up planning.

One thing this rule does is quite a few Expr copies while checking exprs for join keys

What changes are included in this PR?

1. Move management of join key exprs to JoinExprSet struct
2. Reduce copying of clones internally to JoinExprSet
3. New tests for JoinExprSet

Are these changes tested?

Existing CI

Are there any user-facing changes?

No functional changes

Performance tests show 3-5% faster for TPCH / TPDS queries
