[repacker] change run_resolve_overflow_test to check for graph equivalence.
...
Replaces a check for an exact match on the final serialized bytes. The previous check enforced equivalent topological sorting between result and expected, but we only really care that the graph's are equivalent and don't overflow.

[repacker] add graph equality check.
...
Does not compare topological sorting, but looks for equivalence of the two graphs.

[repacker] Expose on internal method in the repacker that allows the caller to pass in/out a graph.
...
Will be used in testing so we can compare graphs instead of packed result.

[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.

[subset] Prepare the repacker for handling 24bit offsets in GSUB/GPOS.
...
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.
