  -----------
  [MLIR][Affine] Fix sibling fusion - missing check (#126626)

Fix sibling fusion for slice maximality check. Producer-consumer fusion
had this check but not sibling fusion. Sibling fusion shouldn't be
performed if the slice isn't "maximal" (i.e., if it isn't the whole of
the source).
