Previously, non-trivial type aliases in extern blocks were dropped by rustfmt because only the type alias name would be passed to a rewritter. This commit fixes that by passing all type information (generics, bounds, and assignments) to a type alias rewritter, and consolidates `rewrite_type_alias` and `rewrite_associated_type` as one function.

This would be useful for me as well. Thanks for the backport. |

This is a straightforward backport of #4164 to resolve rustfmt deleting important code when using the
cxxcrate; see dtolnay/cxx#330 (comment).
