Stop copying LogicalPlan and Exprs in `PushDownLimit`

[alamb]

Is your feature request related to a problem or challenge?

Part of #9637

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

Describe the solution you'd like

I would like to reduce the amount of copying in this pass (even though it doesn't appear in current profiling)

Describe alternatives you've considered

Apply the model from @Lordworms in #10166 to this pass
2. Update OptimizerRule::supports_rewrite` to return true

1. Update OptimizerRule to use rewrite
2. Update the pass itself to not copy the LogicalPlan (ideally using the TreeNode API) - it is implemented for LogicalPlan (API) and Expr (API)

Other examples: #10218

I made #10501 to pull some of the code out into a function to maybe make this easier

Sorry @alamb didn't get a chance to work on it unfortunately. Agree, feel free to work on it.

No worries. Thanks @kavirajk
