%merge: fix compatibility with api.value.type=union

Browse Source 
Reported by Jot Dot.
https://lists.gnu.org/r/help-bison/2020-12/msg00014.html

* data/skeletons/glr.c, data/skeletons/glr2.cc (b4_call_merger): Use
the symbol's slot, not its type.
* examples/c/glr/c++-types.y: Use explicit per-symbol typing together
with api.value.type=union.
(yylex): Use yytoken_kind_t.
