nop_lift macros: ensure that we are using the right interner

Right now someone could put down the wrong list name when using these macros, and everything would still build. Nothing does a type-check to ensure that the `$set` contains element of type `Self::Lifted`. Let's fix that.

For lists this is fairly easy; for the other interners we need to unwrap some newtypes which makes this more complicated.

Do not clone MIR for const-prop lint.
