[subset] add destructor to subset plan.
...
This ensures that it's members get destructed before the plan itself is destructed, as hb_object_destroy calls the destructor for plan.

[object] Only destruct object if it's not trivially-destructible
...
Such that we're legally free to access the object to destruct its
(pointer) fields ourselves afterwards. For things like hb_font_t,
hb_face_t, etc.

[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.
