wireguard: fix fib entry tracking
Type: fix After peers roaming support addition, FIB entry tracking stopped working. For example, it can be observed when an adjacency is stacked on a FIB entry by the plugin and the FIB entry hasn't got ARP resolution yet. Once the FIB entry gets ARP resolution, the adjacency is not re-stacked as it used to. This results in endless ARP requests when a traffic is sent via the adjacency. This is broken because the plugin stopped using "midchain delegate" with peers roaming support addition. The reason is that "midchain delegate" didn't support stacking on a different FIB entry which is needed when peer's endpoint changes. Now it is supported there (added in 36892). With this fix, start using "midchane delegate" again and thus, fix FIB entry tracking. Also, cover this in tests.
