Is your feature request related to a problem or challenge?

Substrait relations have the concept of an emit kind, which can either be:

• Direct: which is the default order and outputs fields based on the Direct Output Order specified in the Substrait spec.
• Emit: which includes a list of the outputs to include based on the Direct output ordering.

Currently, DataFusion ignores the emit_kind field entirely, which can impact the correctness of Substrait plan execution.

For more details see https://substrait.io/relations/basics/#emit-output-ordering

Describe the solution you'd like

DataFusion should handle both Direct and Emit emit kinds.
