[subset] further changes to serializer error handling.
...
- Rename enum type and enum members.
- in_errors() now returns true for any error having been set. hb-subset now looks for offset overflow only errors to divert to repacker.
- Added INT_OVERFLOW and ARRAY_OVERFLOW enum values.

[subset] Add prioritization offset resolution.
...
Vertices can now be prioritized to force them to sort closer to their parent. The resolver will attempt to use this for overflows on non-shared vertices.
