As with directives, this commit splits the monolithic Roles feature
into a backend feature and two frontend features.
The original Roles feature is responsible for providing the API used
by the frontend features.
The RstRoles and MystRoles features use the backend to provide
features for the reStructuredText and MyST syntaxes respectively. Note
that this is already proving useful as the MystRoles feature does
not need the "backtracking" code the RstRoles feature uses to
determine if a completion is an actual role, or a directive's option.
