services/bsd: Implement most of bsd:s
This implements: Socket, Poll, Accept, Bind, Connect, GetPeerName, GetSockName, Listen, Fcntl, SetSockOpt, Shutdown, Recv, RecvFrom, Send, SendTo, Write, and Close The implementation was done referencing: SwIPC, switchbrew, testing with libnx and inspecting its code, general information about bsd sockets online, and analysing official software. Not everything from these service calls is implemented, but everything that is not implemented will be logged in some way.
