Ebrahim Byagowi b143e34ee1 [gsubgpos] Initialize variation index on HB_NO_VAR
hb_shape_plan_key_t::equal expects hb_ot_shape_plan_key_t be initialized by
hb_ot_layout_table_find_feature_variations calls but it won't get initialized
when HB_NO_VAR build config is used.

Behdad Esfahbod c14efb8e68 Fix previous commit
Priority should be given to specific over dispatch.  Broke sanitize before.
This fixes it, by moving prioritization to the context implementation, since
the correct priority cannot be done in the dispatch implementation.  Done
for subset and sanitize only, which need it.
