Remove remaining uses of box syntax from librustdoc Remove the remaining uses of box syntax from librustdoc. Followup of #99066 where these changes were split out because they were responsible for a small but noticeable regression. This PR avoids the regression by boxing some large variants of `ItemKind` to reduce the enum's size by half from 224 bytes to 112 bytes (on x86-64). This should also help with reducing memory usage.
