  [mlir][sparse] Fix bug in new syntax parser (#66024)

Currently, dimlvlmap with identity affine map will be treated as empty
affine map. But the new syntax would treat it as an actual identity
affine map such as {d0} -> {d0}. This mismatch could raise an error when
we are comparing sparse encodings.
