[client] Implement dns routes for Android

[lixmal]

Describe your changes

This PR implements dns routes on android by

• Routing a 240.0.0.0/8 block on startup
• On DNS traffic, assigning IPs from this block and returning those as DNS response
• The client sends packets to these fake IPs, which are then DNATed to the real IPs
• On the interface we assign the real IPs as allowed IPs
• For return traffic we apply the same process in reverse
• Requires the wildcard feature to be enabled, otherwise we cannot replace the IPs in DNS responses
