Move {Ref,Change,Project}Control into permissions package

This is the last commit of a longer series to hide the internal
implementation of Gerrit's permission schema and have all calls go
through PermissionBackend.

This commit moves all Control classes into server/permissions to avoid
direct calling from other classes in server/project.
