pytorch#2952) Summary: # Context * Currently torchrec IR serializer does not support exporting variable batch KJT, because the `stride_per_rank_per_rank` and `inverse_indices` fields are needed for deserializing VBE KJTs but they are included in the KJT's PyTree flatten/unflatten function. * The diff updates KJT's PyTree flatten/unflatten function to include `stride_per_rank_per_rank` and `inverse_indices`. # Ref Differential Revision: D74295924
