Summary: This commit moves the m_spawned_pids member from the common LLGS/Platform class to the plaform specific part. This enables us to remove LLGS code, which was attempting to manage the m_spawned_pids contents, but at the same time making sure, there is only one debugged process. If we ever want to do multi-process debugging, we will probably want to replace this with a set of NativeProcessProtocolSP anyway. The only functional change is that support for qKillSpawnedProcess packet is removed from LLGS, but this was not used there anyway (we have the k packet for that).
