Check permission if user has rights of table (data definition)

[baumannsven]

If the user has no rights of a table (data definition). So we must implement a permission check to the list view. This is missing.

We do not check this in the moment. ContaoCoreBundle checked if the user has rights of the backend module. See here https://github.com/contao/core-bundle/blob/16b52a055d4c12d09b47f21798efe8331f065e67/src/Resources/contao/classes/Backend.php#L308.

I do not close this. If the dcg becomes the own entry point, i think we must implement an own check.

We must have a current use case!
