Update MemRefAccess::getAccessMap to always canonicalize map + operands 

- with this we won't see duplicate / unused operands when getting access maps,
  or when constructing FlatAffineConstraints based on such maps

- we can probably change fullyComposeAffineMapAndOperands to ensure this
  TODO(b/123879896).
