quic: implement various utilities classes to be used by the quic impl

In an attempt to make https://github.com/nodejs/node/pull/44325 easier to review, I'm going to start pulling chunks of it out into separate PRs. This PR adds implementations for a number of utility classes used in the implementation. Unfortunately, breaking things up like this makes it a bit more difficult to review for correct usage since these are not yet being used, but my hope is that by splitting things up like this folks can actually give reasonable review for the individual pieces. I anticipate opening several more smaller PRs before we get to the primary chunk of the actual implementation.

This PR is split into several individual commits. It will be easiest to review each commit individually.
