Garmelon 08eb78a5b2 chore: switch to new test/bench suite (#12590)
This PR sets up the new integrated test/bench suite. It then migrates
all benchmarks and some related tests to the new suite. There's also
some documentation and some linting.

For now, a lot of the old tests are left alone so this PR doesn't become
even larger than it already is. Eventually, all tests should be migrated
to the new suite though so there isn't a confusing mix of two systems.

# Abstracting nested proofs hid 'sorry' warnings
https://github.com/leanprover/lean4/issues/10196

Simplified version. The second `g'` did not use to have a warning.
It re-used the `g._proof_1` proof.

Examples from the issue. The `ByteString.Pos.next` definition did not use to have a warning.
