Description

This came up in the comments of ARROW-14575, but would be helpful even without doing anything with the namespace: instead of nse_funcs <- ..., create a registry + function to register each function and then use that registry in place of nse_funcs.

This will:

• Give us a bit more freedom for defining bindings in separate files (though which nse_funcs+collate we could do the same). E.g. have one file per package
• Possibly give a place to add some documentation (though see ARROW-15011)
