Stop copying LogicalPlan and Exprs in `OptimizeProjections`

[alamb]

Is your feature request related to a problem or challenge?

As part of making the planner faster, we are updating the passes to avoid copying LogicalPlan and Expr (see #9637)

Recent profiling (#9637 (comment)) shows that a non trivial amount of plan time happens in OptimizeProjections

Describe the solution you'd like

I would like to reduce the amount of copying in this passso that it no longer appears in profiling traces

Describe alternatives you've considered
