Merge bitcoin/bitcoin#23604: Use Sock in CNode

Browse source 
ef5014d256 style: wrap long lines in CNode creation and add some comments (Vasil Dimov)
b683491648 scripted-diff: rename CNode::cs_hSocket to CNode::m_sock_mutex (Vasil Dimov)
c41a1162ac net: use Sock in CNode (Vasil Dimov)
c5dd72e146 fuzz: move FuzzedSock earlier in src/test/fuzz/util.h (Vasil Dimov)

Pull request description:

  _This is a piece of #21878, chopped off to ease review._

  Change `CNode` to use a pointer to `Sock` instead of a bare `SOCKET`.
  This will help mocking / testing / fuzzing more code.

ACKs for top commit:
  jonatack:
    re-ACK ef5014d256 changes since last review are the removal of an unneeded dtor and the addition of a style commit
  w0xlt:
    reACK ef5014d
  PastaPastaPasta:
    utACK ef5014d256, I have reviewed the code, and believe it makes sense to merge
  theStack:
    Cod-review ACK ef5014d256
