### Is your feature request related to a problem or challenge? https://github.com/apache/datafusion/pull/12920 added FFI Physical Plans. These cannot be encoded or decoded with the DefaultPhysicalExtensionCodec. We cannot serialize these plans that include foreign elements. I would like to add a way to provide for serialization/deserialization across the FFI boundary. ### Describe the solution you'd like Add an additional struct along the lines of `FFI_PhysicalExtensionCodec` that implements `PhysicalExtensionCodec`. ### Describe alternatives you've considered None that I can think of, other than to find work arounds to not serialize these plans. ### Additional context This is needed to support adding a `FFI_QueryPlanner` so that we can do things like use a different library to generate physical plans. The use case I currently have in mind is `datafusion-ray` where we want to make a query planner that can automatically distribute work across multiple nodes in a cluster. -- This is an automated message from the Apache Git Service.
