wireguard: add dos mitigation support
Type: feature
With this change:
- if the number of received handshake messages exceeds the limit
calculated based on the peers number, under load state will activate;
- if being under load a handshake message with a valid mac1 is
received, but mac2 is invalid, a cookie reply will be sent.
Also, cover these with tests.
