quic/stream: create gen. getWriter for stream/iter

[martenrichter]

The get writer method of QuicStream is mostly
generell enough to be usuable in other contexts.
This PR is an attempt to move the code out
of the QuicStream object to be usuable in other
parts of node.js.

Fixes #66508

That is a first idea of how to move get writer out of QuicStream .
After the interface is discussed and agreed upon, I would then, in another commit, move the code for this part to a place related to stream/iter (where?).
We also need to discuss whether this should remain an internal method or part of the public api.
(In this case, additional checks are necessary)

P.S.: There seem to be some bugs remaining. (I thought I had run all tests, but it seems that I only ran lint and not a full build.) But discussing the structure should work anyway.

Ok, now, everything works according to the local tests.

I do not understand the build failures. It complains about an unknown compiler option? Do I need to rebase?
