Objective

Currently, you can add Option<Res<T> or Option<ResMut<T> as a SystemParam, if the Resource could potentially not exist, but this functionality doesn't exist for NonSend and NonSendMut

Solution

Adds implementations to use Option<NonSend<T>> and Option<NonSendMut> as SystemParams.

This does currently conflict with #2330 as it changes/moves NonSend and its Doc-Comment.

This looks good to me!
Other than the conflicts with #2330 witch either you or I will have to fix depending on who's PR gets merged first 😛
