[mlir][NFC] Fully spell mlir types names in LoopLikeOpInterface, so it can be used in ops defined outside mlir namespace

         Returns true if the given value is defined outside of the loop.
         A sensible implementation could be to check whether the value's defining
         operation lies outside of the loops body region. If the loop uses
         explicit capture of dependencies, an implementation could check whether
         the value corresponds to a captured dependency.
