[subset] For [Chain]ContextFormat3 make sure the sub table intersects the retained glyphset before recursing to its lookups.
...
Otherwise the lookup closure will potentially pull in lookups which cannot be accessed via the retained glyph set.

[subset] shrink the serialize buffer when pruning empty offsets in ChainContextFormat2.

Currently the code reduces the array length, but does not trim back the space allocated in the serializer for those empty offsets.

[subset] In ChainContextFormat3 don't skip subsetting if backtrack or lookahead are empty.
...
It's valid to have a ChainContextFormat3 with either an empty backtrack or lookahead. Only drop the lookup if the input sequence is empty.

Use dispatch for get_glyph_alternates_t
...
First time we do this in a way that if target object doesn't have the matching
function we basically "ignore". Risky but I feel like is the right decision
for this case.
I'm going to put back the template varargs and use those, which would make
the dispatcher be just that: "dispatcher", and wouldn't need to carry the
call context. That would be a refreshing change I think.

Priority should be given to specific over dispatch. Broke sanitize before.
This fixes it, by moving prioritization to the context implementation, since
