Descriptor for a GRU backward propagation primitive.

Constructs a descriptor for a GRU backward propagation primitive.
The following arguments may point to a zero memory descriptor:
src_iter_desc together with diff_src_iter_desc,bias_desc together with diff_bias_desc,dst_iter_desc together with diff_dst_iter_desc.This would then indicate that the GRU backward propagation primitive should not use them and should default to zero values instead.
