Standardization of combinations tests

[mikeingold]

Changes

• Standardized combinations tests by wrapping testable items in a data structure and passing them to a test suite.
  • Reduces boilerplate and subtle variations between @testitems.
  • Added Unitful integrands to several tests that were using simple scalars.
  • Added commented-out test infrastructure for upcoming AutoEnzyme in add AD (Enzyme) support via EnzymeExt #129.
  • Re-organized to have @testsnippets hosted in the source file where they're used.

Thanks a lot! This looks really nice. I left some suggestions below, but this is on a good way.
