  Awkward v2 mixins not propagated upwards
  ### Version of Awkward Array
  
  2.0.0rc1
  
  ### Description and code to reproduce
  
  Coffea tests with awkwardv2 fail with: `E   AttributeError: module 'awkward.behaviors' has no attribute 'mixin_class'`
  
  `awkward.mixin_class` has moved to `awkward.behaviors.mixins.mixin_class`, along with all other mixin decorators.
