Initializes an LBR_GRU descriptor for backward propagation using prop_kind, direction, and memory descriptors.

flags is a parameter to the LBR GRU descriptor and is currently ignored.

Note
All memory descriptors are allowed to be initialized with dnnl::memory::format_tag::any value of format_kind.

src_iter_desc (simultaneously with diff_src_iter_desc), bias_desc (simultaneously with diff_bias_desc), and dst_iter_desc (simultaneously with diff_src_iter_desc) are allowed point to a zero memory descriptor, which would indicate that the LBR GRU primitive should not use them and consider them to be zero values.
