Make Var less dependent on NPAPI. The goal is to remove all of these

dependencies and then move Var and the associated tracking stuff to the
shared_impl, where it can be used to replace the similar code in the proxy.
There should be no difference in functionality.

- I moved the Var/NPAPI conversion stuff from the Var and ObjectVar object into
  NPAPI glue.

- I moved the Var scripting interface implementation (which forwards to NPAPI)
  to the ppb_var_impl file which is nice because it also matches other
  interfaces.

- I moved the ObjectVar lifetime tracking from the instance into the
  ResourceTracker with the other var stuff.  It turns out we were already
  tracking the object vars there, so I did a little cleanup.

- I changed the PluginModule and PluginInstance in the var object to PP_Module
  and PP_Instance.

The only remaining NPAPI stuff to worry about are the calls to WebBindings in
the ObjectVar constructor & destructor. I will probably move this to the
resource tracker when I move the var file out.
