To support dumping the reproducer's GDB remote packets, we need the (de)serialization logic to live in Utility rather than the GDB remote plugin. This patch renames StreamGDBRemote to GDBRemote and moves the relevant packet code there. Its uses in the GDBRemoteCommunicationHistory and the GDBRemoteCommunicationReplayServer are updated as well.
