refactor: move base http3 transport into netxlite (#412)
This diff is part of https://github.com/ooni/probe/issues/1505.

You will notice that I have not adapted all the (great) tests we had
previously. They should live at another layer, and namely the one that
deals with performing measurements.

When I'm refactoring such a layer I'll ensure those tests that I have
not adapted here are reintroduced into the tree.
