Allow offloading Linux CI load to RunsOn

[gsmet]

This is now ready.

It only targets Linux CI runs as Windows images on RunsOn don't offer Git Bash for now and thus are not usable for us.

Also it doesn't offload the small technical jobs, only the ones that need massive resources.

It makes use of:

• https://github.com/quarkusio/runs-on-action - to configure things
• https://github.com/quarkusio/cache-action - to switch between standard GitHub Actions cache and RunsOn cache (you cannot use a variable for the action coordinates so I use a composite action)

[gsmet]

@cescoffier @maxandersen @gastaldi this is now ready for review. I recommend reviewing commit per commit if you're interested.

I will merge it on Monday morning so that we can get the results on a full week of operation.
