[repacker] fix incorrect coverage table size estimation.
...
During splitting of PairPosFormat2 the code was assuming the maximum size of the generated coverage table would be equal too the current size. This is incorrect size the new coverage table may not preserve the ranges found in the original coverage table (since we are splitting based on class, not coverage) and in the worst case may convert from format2 to format1. So use the size of a format1 table as the max size.

[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.
