ARROW-16158: [C++][R] Rename ARROW_ENGINE to ARROW_SUBSTRAIT At the moment there is not enough non-Substrait functionality to justify a dedicated engine module. In the future there likely will be and so I have some of the general structure around in the C++ (e.g. `ARROW_ENGINE_EXPORT`) but removed any external facing references.
