refactor: ParquetExec logical expr. => phys. expr.

Use `Arc<dyn PhysicalExpr>` instead of `Expr` within `ParquetExec` and
move lowering from logical to physical expression into plan lowering
(e.g. `ListingTable`).

This is in line w/ all other physical plan nodes (e.g. `FilterExpr`) and
simplifies reasoning within physical optimizer but also allows correct
passing of `ExecutionProps` into the conversion.

Closes #4695.
