mruby-compiler: remove unused mrb_ast_when_node structure

Browse Source 
removed struct mrb_ast_when_node and when_node() casting macro which
were never actually used. NODE_CASE uses cons lists to represent
when clauses, not dedicated when_node structures. the structure
definition and macro were dead code left over from earlier design.

case/when implementation uses: cons(cons(conditions, body), next_when)
where each when clause is a cons cell in a list, not a typed node.
