chore(ci): run e2e on isolated spots (#6287)

- ability to call into builder from a non-builder runner, will
eventually move away from self-hosted runners as they had sharp edges
- run e2e on isolated spot for better reproducibility, rerun failed
works with e2e seamlessly
- move bench to new spot pattern that will eventually run other
periphery tests
- allow runners now run on `ubuntu` to align with calling into builder
(otherwise cache wouldn't be shared)
- many passes on CI to make patterns for the new paradigm of
coordinating builders and spot
