Kernel: Move socket role tracking to the Socket class itself
This is more logical and allows us to solve the problem of non-blocking TCP sockets getting stuck in SocketRole::None. The only complication is that a single LocalSocket may be shared between two file descriptions (on the connect and accept sides), and should have two different roles depending from which side you look at it. To deal with it, Socket::role() is made a virtual method that accepts a file description, and LocalSocket internally tracks which FileDescription is the which one and returns a correct role.
