The AddPermissionImpl method is the implementation for the AddPermission method.
If a permission of the same type as the added permission already exists in the PermissionSet, the new permission is the union of the existing permission object and the specified permission object. For example, if a permission that implements IUnrestrictedPermission is added to an UnrestrictedPermissionSet, the resulting union is the original UnrestrictedPermissionSet.
