Expose `PhysicalOptimizerRule` via FFI

[timsaucer]

Is your feature request related to a problem or challenge?

It is desirable for downstream users, specifically datafusion-python, to add methods to enable users to have custom physical plan optimizers. One specific case is datafusion-distributed which works by rewriting the physical plan to do network shuffling. If we expose PhysicalOptimizerRule in the FFI crate, it would enable adding this feature downstream.

Describe the solution you'd like

Create a FFI_PhysicalOptimizerRule and implement it's methods in a FFI-safe manner.

Describe alternatives you've considered

No response

Additional context

In order to support this we need two additional PRs to merge first:

• Add support for FFI config extensions #19469
• feat: support repartitioning of FFI execution plans #20449

FYI @gabotechs @robtandy this work epic is what will enable using datafusion-distributed with datafusion-python. Of course I have PRs for that repo, but this is the required upstream work.
