Remove explicit generation of documentation in Debug configuration

We now generate the documentation in _all_ configurations, as part of the `Directory.Build.props` (4919695). There's also no need to generate the legacy debug symbols, so I'm removing the entire condition. (This was already removed for other projects, but left in for `OnTopic` until it could be reevaluated.)
