Which issue does this PR close?

Doesn't close any, but is related to #4370.

Rationale for this change

While working on #4370 I've discovered that we don't optimize expressions within TableScan nodes.

What changes are included in this PR?

Include TableScan expressions within the logical optimization.

Are these changes tested?

See plan change in tpch_q22_correlated.

Are there any user-facing changes?

Better optimized plans.
