When nodes are duplicated it's fine to just reuse head, tail from the node being cloned since we don't modify the contents.

[repacker] put each 32 bit subgraph into it's own packing space.
...
Each subgraph pointed to by a 32 bit offset should be packed into it's own space. This adds a space property to vertices which affects the distance calculation. This effectively places the distances for all of the nodes of a 32 bit subgraph into a distinct range. Thus all of the nodes of the subgraph will be packed together.

Adds isolate_subgraph operation to the repacker. This severs any links from outside a subgraph by duplicating the affected vertices. This will be used to isolate the subgraphs of a extension subtable from the rest of object graph. Thus allowing the extension subtable to be packed far away from the rest of the objects.

[subset] Fix subset_offset_array adding unused space to serializer.
...
ArrayOf.serialize_append allocates space for the new item, but ArrayOf.pop() does not recover the allocated space. So in the case where the revert path was entered the extra space added by serialize_append gets left in the serialization buffer. This moves the snapshot to before ArrayOf.serialize_append is called so that revert cleans up the buffer extend.
