Change NaCl IPC PPAPI proxy startup to support a NaCl-Browser process

channel.

NaClProcessHost now creates an initial NaCl-Browser channel, then uses
it to send a message to create the NaCl-Renderer channel. The main() for
the IPC-IRT creates a PpapiDispatcher object to manage this channel and
manage the PluginDispatchers for each renderer.
