Convert array from AMQP 1.0 to AMQP 0.9.1 (backport #12571)

[mergify]

Fix the following crash when an AMQP 0.9.1 client consumes an AMQP 1.0 encoded message that contains an array value in message annotations:

crasher:
  initial call: rabbit_channel:init/1
  pid: <0.685.0>

  exception exit: {function_clause,
                      [{mc_amqpl,to_091,

                            {array,utf8,[{utf8,<<"e1">>},{utf8,<<"e2">>}]}],
                           [{file,"mc_amqpl.erl"},{line,737}]},
                       {mc_amqpl,'-convert_from/3-fun-3-',1,
