Migrate benchmarks to Divan

[nvzqz]

Changed from the nightly benchmark harness to Divan, and renamed benchmark functions to be more consistent and to remove mentions of the parent group.

I considered defining benchmarks to be within the same file, but decided to keep them separated so that this PR can be relatively non-invasive.
