Move object_id in object fields.

Browse source 
And get rid of the `obj_to_id_tbl`

It's no longer needed, the `object_id` is now stored inline
in the object alongside instance variables.

We still need the inverse table in case `_id2ref` is invoked, but
we lazily build it by walking the heap if that happens.

The `object_id` concern is also no longer a GC implementation
concern, but a generic implementation.
