Make binary operator formatting consistent between logical and physical plans

[andygrove]

Which issue does this PR close?

Part of #3330

Rationale for this change

Logical plans use the Operator Display trait and Physical plans use the Operator Debug trait, meaning we end up with * in the logical plan and Multiply in the physical plan. Sometimes we end up with a mix of both in the final schema.

What changes are included in this PR?

Physical plan now uses Display trait.

Are there any user-facing changes?

No

Makes sense to me -- thank you @andygrove 👍
