asn1ct_constructed_per: Refactor gen_dec_choice2()
gen_dec_choice2() is unnecessarily complicated. Code is duplicated merely to avoid outputting a ";" separator after the last item, and there is code to skip extensionmarks that are never actually present. While at it, eliminate the the wrap_gen_dec_line() function which is not needed. It puts a {component_type,C} key in the process dictionary, but that is actually never used. Besides that, it only shuffles the argument.
