Merge bitcoin/bitcoin#27324: net: #27257 follow-ups
cd0c8eeb09 [net] Pass nRecvFloodSize to CNode (dergoegge)
860402ef2e [net] Remove trivial GetConnectionType() getter (dergoegge)
b5a85b365a [net] Delete CNetMessage copy constructor/assignment op (dergoegge)

Pull request description:

  Follow-up PR for #27257

  * Deletes the copy constructor/assignment operator of `CNetMessage`
  * Removes trivial getter for the connection type
  * Avoids passing `nRecvFloodSize` to CNode methods by passing it to `CNode` on creation
