[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.

This is actually an interesting thing that {h,v}mtx allocates as
much as a font pretends to have glyphs but the solution is not
that obvious as regular fonts can have less than actually containing
metrics in their {h,v}mtx. This change raises the bar to consider this
hmtx 4 byte for every glyph case.
Initially we wanted to just find things allocating crazy amount of
memory but having the assert has led to interesting findings also
so let's don't remove the assert and see what we can find elsewhere.
