This commit does the following. - Changes it from `Lrc<Box<dyn ToAttrTokenStream>>` to `Lrc<LazyAttrTokenStreamInner>`. - Reworks `LazyAttrTokenStreamImpl` as `LazyAttrTokenStreamInner`, which is a two-variant enum. - Removes the `ToAttrTokenStream` trait and the two impls of it. The recursion limit must be increased in some crates otherwise rustdoc aborts.
