`rustc_mir_dataflow` has a typedef `AbstractElem` that is equal to `ProjectionElem<AbstractOperand, AbstractType>`. `AbstractOperand` and `AbstractType` are both unit types. There is also has a trait `Lift` to convert a `PlaceElem` to an `AbstractElem`. But `rustc_mir_middle` already has a typedef `ProjectionKind` that is equal to `ProjectionElem<(), ()>`, which is equivalent to `AbstractElem`. So this commit reuses `ProjectionKind` in `rustc_mir_dataflow`, removes `AbstractElem`, and simplifies the `Lift` trait.
