Avoid recursive trait resolution for `IntoIterator`

[Ogeon]

A workaround for another case of #283. This time for IntoIterator. It avoids the issue by only providing implementations for specific collection types.

• Fixes #283

Breaking Change

This makes IntoIterator no longer generic over the collection type, but explicitly covers [T; N], &[T], &mut [T] , Vec<T>, and Box<[T]>.
