[subset] Use plan->glyphset_gsub instead of plan->glyphset for GSUB/GPOS
...
This matches fontTools behaviour. glyphset_gsub does not contain gids added from closing over composite glyphs in glyf, since these cannot particpate in GSUB/GPOS processing.

Simplify get_glyph_alternates() dispatcher
...
Trying to make it **very simple** to add a specialized dispatcher for
one API to be routed to just a few objects (one in this case).

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.
