Review single line where clauses diffs

[calebcartwright]

rust-lang/rust#119515 modified the Style Guide for 2024 to switch to single line formatting for type aliases and body-less functions with rules that included some new "short" thresholds.

This has been implemented in rustfmt with some suggested values for those "short" thresholds, with some examples shown in https://rust-lang.zulipchat.com/#narrow/channel/346005-t-style/topic/single.20line.20where.20clauses

Similar to exercises we've done with other 2024 changes, I'd like to review the formatting results under the new rules and thresholds to (a) confirm it's what the team wants and (b) see if there's any t-style input on those "short" thresholds

(sidebar but I will add that there was a comment from outside the team that expressed a dislike for the single line functions when the function had a return type)

This issue has served its purpose, topic was discussed and resolved in the 2024-10-23 t-style meeting. Closing accordingly
