Pipe class abstract interface

An anonymous pipe that can be used to send data in a single direction i.e. data written to write can be read using read.

On macOS and Linux (excluding Android), either the read or write portion of the pipe can be transmitted to another process and used for interprocess communication.

For example:

final pipe = await Pipe.create();
final socket = await RawSocket.connect(address, 0);
socket.sendMessage(<SocketControlMessage>[
SocketControlMessage.fromHandles(
    <ResourceHandle>[ResourceHandle.fromReadPipe(pipe.read)])
], 'Hello'.codeUnits);
pipe.write.add('Hello over pipe!'.codeUnits);
await pipe.write.flush();
await pipe.write.close();
