Move mindependency and latestdependency common dependencies to a file

[scbedd]

• Process that file as part of CI to ensure we re-use the same wheel (instead of hitting issues when multiple tox environments try to build it at once)
• In mindependency or latestdependency we only use use default tool install + your package reqs. NO dev_requirements are used.

This is the piece that I forgot when merging the the other PR. We need it to work both with a default tox install, but also in CI where parallelism comes into play.

This PR should meet the needs of both.

Confirmed on internal run.

pre-deps literally isn't a thing. Just cleaning it up.
