Required for #4402.

Objective

  • derived SystemParam implementations were never ReadOnlySystemParamFetch
  • We want them to be, e.g. for EventReader

Solution

  • If possible, 'forward' the impl of ReadOnlySystemParamFetch.

This probably deserves a compile fail test that deriving system param on something like Query<'a, 'b, &'static mut Foo> doesnt get ReadOnlySystemParamFetch

All this change does is pass through an existing implementation, and the safety comment expresses this.
There's not really any way for it to go wrong, unless another implementation is also wrong.

(Also I don't know where that compile fail test would go)

@DJMcNab can you rebase? It looks like the changes in #3863 broke this.

I think I'm already rebased past that PR?

At least I think that's why I rebased most recently
