For a vector TransferOpType xferOp, an empty indices vector, and an AffineMap representing offsets to apply to indices, the function fills indices with the original indices plus the offsets.
The offsets are applied by taking into account the permutation map of the transfer op. If the offsetMap has dimension placeholders, those should be provided in dimValues.
