[linked-list] range-based for loop iteration over all entries (#6945)

Browse Source 
This commit enables use of range-based `for` loop for iterating over
all the entries in a `LinkedList`. It adds private implementations of
`Iterator` and `ConstIterator` which inherit from `ItemPtrIterator`
and use the `GetNext()` to go to the next entry. The range-based
`for` loop practically acts as a syntactic sugar helping simplify the
code and does not add any code size (or any expected run-time)
overhead.
