PPAPI/NaCl: Make NaClIPCAdapter transfer handles more generally

This does a couple of things:
- It defines a new wrapper for passing any kind of handle through the PPAPI proxy (SerializedHandle).
- It updates nacl_ipc_adapter to have a more general way to pick apart messages based on their static types (which include the types of all the params).
- It adds support for PPB_Graphics2D and PPB_Graphics3D to the NaCl IPC proxy (e.g., NaCl SDK examples pi_generator and tumbler work in the new proxy with this patch).

The downside is it requires pulling parts of ppapi/shared_impl and ppapi/proxy in to the NaCl Win64 build.
