[PPAPI] Added new Pepper interface PPB_VarResource_Dev.

This interface allows the plugin to create resource vars from PP_Resource, and
also to extract the PP_Resource from a resource var. This facilitates sending
and receiving resources through the JavaScript messaging interface.

Currently only available to plugins with DEV permission.
