Introduce IPC::ChannelProxy::Create*() and IPC::SynChannel::Create*()

This change hides constructors of these classes so that we can turn
them polymorphic classes.

Note that having almost identical ChannelProxy::Init*() isn't great
and they will be replaced by a factory-like abstraction in coming
changes.
