Lifted intersperse and intersperse_with Fused transformation and updated documentation + tests

This PR once again builds on top of rust-lang/rust#152855. From the discussion in rust-lang/rust#152855, libs team came to the conclusion that `intersperse`/`intersperse_with` shouldn't transform the given iterator to a fused iterator always and a separator should be emitted between `Some(_)` items for non fused iterators (particularly just right before the subsequent `Some(_)`).

On top of the change Zakarumych added in the PR, I lifted the `FusedIterator` trait and transformation of the inner `iter` for `Intersperse`/`IntersperseWith`, so that we can display this behavior. I've adjusted the documentation and tests accordingly to reflect this change as well.
