Add support for directions on parameters and attributed types. The latter is necessary to support the former, but is not limited to the direction use case. An attributed type is a P4 type with attributes (like its direction, whether it is read only, etc.) Other attributes will be added in the future. Changes necessary to support attributed types include: 1. Global instances tracked during compilation are not attributed types and not simply types. 2. (future) Type checking will have to make sure that a types attributes do not affect type compatibility. Signed-off-by: Will Hawkins <hawkinsw@obs.cr>
