Rollup merge of #83560 - m-ou-se:io-chain-debug, r=sfackler
Derive Debug for io::Chain instead of manually implementing it.

This derives Debug for io::Chain instead of manually implementing it.

The manual implementation has the same bounds, so I don't think there's any reason for a manual implementation. The names used in the derive implementation are even nicer (`first`/`second`) than the manual implementation (`t`/`u`), and include the `done_first` field too.
