Separate monolithic GDBRemoteCommunicationServer class into 4 part

GDBRemoteCommunicationServer: Basic packet handling, handler registration
LLDBCommonPacketHandler: Common packet handling for lldb-platform and lldb-gdbserver
LLDBPlatformPacketHandler: lldb-platform specific packet handling
LLGSPacketHandler: lldb-gdbserver specific packet handling
