Introduce IPC::Channel::Create*() to ensure it being heap-allocated.

This change introduces IPC::Channel::Create*() API to turn
IPC::Channel into a heap allocated object. This will allow us to
make Channel a polymorphic class.

This change also tries to hide Channel::Mode from public API
so that we can simplify channel creation code paths cleaner in
following changes. ChannelProxy has to follow same pattern to
finish this cleanup. Such changes will follow.
