Support for generating JSON formatted substrait plan

[richtia]

A few other substrait producers are able to generate a JSON formatted substrait plan (Isthmus, DuckDB). It would be nice if datafusion could do this as well. It would make it much easier to compare the generated substrait plans.

One alternative would to be to use the protobuf json_format package to export/import the JSON.

The substrait crate supports the Protobuf JSON Mapping via the serde feature: https://docs.rs/substrait/latest/substrait/#serde-support.
