Add future incompatibility lint for array.into_iter() #66017

  1. Add future incompatibility lint for array.into_iter() 

    As we might want to add `IntoIterator` impls for arrays in the future,
and since that introduces a breaking change, this lint warns and
suggests using `iter()` instead (which is shorter and more explicit).
