- Add the condition for handling loopback addresses in `RouteOutput ()`.
- Add about this change in "Scope and Limitations" of Nix documentation.

1. MPDUs with expired lifetime are already discarded:
- when a QosTxop releases/requests the channel
- when we check if there are pending BlockAckReq frames
hence, it is useless (and sometimes troublesome) to check
for MPDUs with expired lifetime at every packet dequeue
2. Dequeue{ByTid, ByAddress, ...} were not used and hence
removed (one can use a Peek* method and then Dequeue())
3. Given that a WifiMacQueueItem stores an iterator, add a
Dequeue method (the only one in addition to the default one)
that receives a WifiMacQueueItem and dequeues it in constant time
So far, when A-MSDU aggregation is performed, MPDUs containing the
constituent MSDUs are kept in the queue until the MPDU containing
the A-MSDU (which is kept out of the queue) is transmitted.
Now, as soon as A-MSDU aggregation is performed, MPDUs containing
the constituent MSDUs are dequeued and the MPDU containing the
A-MSDU is enqueued in their place.
The specialized functions were kept for better code readability
and only had a few code differences (Otherwise the prior `RunIf`
would have worked but the code would have looked complex).
Using `if constexpr` makes code less redundant and easier to
read as the common code is grouped now.

Since ns-3 supports C++17 constructs now, we can make use
of `if constexpr` as it evaluates the condition inside it
only for that instantiation (distinction happens at compile
time itself).

This change improves the performance of Nix in bigger topologies as
it uses the `unordered_map` which has better performance than
`GetObject<Ip> ()` as it reads through the list.
This `unordered_map` will be created along with `IpAddress` to `Ptr<Node>`
`unordered_map`. Since it is a static member, it will be only time over
all the `NixVectorRouting` instances.
