IsolateNameServer class Null safety

Static methods to allow for simple sharing of SendPorts across Isolates.

All isolates share a global mapping of names to ports. An isolate can register a SendPort with a given name using registerPortWithName; another isolate can then look up that port using lookupPortByName.

To create a SendPort, first create a ReceivePort, then use ReceivePort.sendPort.

Since multiple isolates can each obtain the same SendPort associated with a particular ReceivePort, the protocol built on top of this mechanism should typically consist of a single message. If more elaborate two-way communication or multiple-message communication is necessary, it is recommended to establish a separate communication channel in that first message (e.g. by passing a dedicated SendPort).
