Fixes #4406 by @sarayourfriend

Description

This PR updates the CI + CD workflow to use ov. This should make ov more resilient to accidental breakages.

🚧 WIP:

• Implement caching for ov and its contents.
• Speed up workflow by removing redundant steps.
• Simplify and deduplicate workflow code.

I'm going to come back to this from a Linux machine.

This is definitely not ready for review, lol. How did that happen?

I would have thought this would need to include a call to ov just install as well; or is the plan to install specifically for each CI step? If the whole ov container and volume is going to be cached between jobs then installing once at the start would save some time on subsequent jobs 🤔. I don't know if the volume will work that way, though.
