[repacker] during table splits don't mutate shared coverage/classdef in place.
...
If other subtables are sharing coverage with a subtable being split we have to duplicate the coverage/classdef tables before they are modified during the shrink operation.

Splits are done in a way that it shouldn't be possible to share the classDef2 between split PairPos2's so pre-emptively duplicate it.
