Allow testing of earliest/latest dependencies (#1613)

Mostly identical to gh-1606, which allows the testing of oldest/latest dependencies.  What oldest/latest dependencies means exactly has to be set by each project in their `dependencies.yaml` file for the test env.

See rapidsai/shared-workflows#228 for the workflow changes.

This is part of preparing for 2.0 (which should just work, but in the end no need to include it in the same PR).

*Modifications from draft PR:*
- I renamed it to `oldest`, as suggested by Matthew.
- Noticed that the name is different between wheel and conda workflows, so modified both to include all matrix information.

(Draft, since the shared workflow should be pushed in first to revert the branch renaming probably.  Need to test that the wheel workflow is correct.)
