Remove obsolete methods from IPC::Channel and related classes.
This removes GetSelfPID(), GetClientFileDescriptor() and
TakeClientFileDescriptor(), along with corresponding methods on
content::ChildProcessHost, content::SandboxedProcessLauncherDelegate,
NaClIPCAdapter and ppapi::proxy::ProxyChannel. This also removes the
unused IPC descriptors kPrimaryIPCChannel and kStatsTableSharedMemFd.
