  Log Message:
  -----------
  [mlir][linalg] Only compose PadTensorOps if no ExtractSliceOp is rank-reducing.

Do not compose pad tensor operations if the extract slice of the outer pad tensor operation is rank reducing. The inner extract slice op cannot be rank-reducing since it source type must match the desired type of the padding.

Depends On D115359
