  [mlir] Fix SubTensorInsertOp semantics

Like SubView, SubTensor/SubTensorInsertOp are allowed to have rank-reducing/expanding semantics. In the case of SubTensorInsertOp , the rank of offsets/sizes/strides should be the rank of the destination tensor.

Also, add a builder flavor for SubTensorOp to return a rank-reduced tensor.
