rustdoc: fix spacing of non-toggled impl blocks We [recently removed the "up here" arrows on item-infos](https://github.com/rust-lang/rust/pull/92651), and adjusted vertical spacing so that even without the arrow, it would be visually clear which item the item-info belonged to. The new CSS styles for vertical spacing only applied to toggles, though. This missed non-toggled impl blocks - for instance, those without any methods, like https://doc.rust-lang.org/nightly/std/marker/trait.Send.html#implementors. The result was lists of implementors that were spaced too closely. This PR fixes the spacing by making it apply to non-toggled impl blocks as well. This also fixes an issue where item-infos were displayed too far below their items. That was a result of display: table on .item-info .stab. Changed that to display: inline-block.
