libcamera: ipc: unix: Make socket operation asynchronous
Blocking socket operation when receiving messages may lead to long
delays, and possibly a complete deadlock, if the remote side delays
sending of the payload after the header, or doesn't send the payload at
all. To avoid this, make the socket non-blocking and implement a simple
state machine to receive the header synchronously with the socket read
notification. The payload read is still synchronous with the receive()
method to avoid data copies.
