better organization of benches

[hymm]

It seems sort of random right now. Maybe at least organize them alphabetically. Might also make sense to have separate pages for the different folders, camera, ecs, math, picking, platform, reflect, render, scene, tasks, and transform.

by default they are ordered by z-score, which should surface the benchmarks with the most recent variations first
there is a link to have them ordered by name
