Rollup merge of #120750 - compiler-errors:itctx-by-val, r=cjgillot

No need to take `ImplTraitContext` by ref We used to mutate `ImplTraitContext`, so it used to be `&mut` mutable ref. Then I think it used to have non-`Copy` data in it, so we took it by `&` ref. Now, none of that remains, so just copy it around.
