Subject: Simplify `LazyAttrTokenStream`.

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.
