…s for VBE KJTs. Summary: For VBE KJTs, ppdate the `_maybe_compute_stride_kjt` logic to calculate stride based off of `inverse_indices` when its set. Currently, stride of VBE KJT with `stride_per_key_per_rank` is calculated as the max "stride per key". This is different from the batch size of the EBC output KeyedTensor which is based off of inverse_indices. This causes issues in IR module serialization. Differential Revision: D76997485
