[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.

The boring expansion (https://github.com/be-fonts/boring-expansion-spec ) plans to introduce 24bit offsets into GSUB/GPOS. This changes the repacker to treat 24 bit offsets similar to 32 bit offsets and assign the top level 24 bit offsets into spaces to improve packing.
