[client] Add stateful userspace firewall and remove egress filters ( #3093 )
...
- Add stateful firewall functionality for UDP/TCP/ICMP in userspace firewalll
- Removes all egress drop rules/filters, still needs refactoring so we don't add output rules to any chains/filters.
- on Linux, if the OUTPUT policy is DROP then we don't do anything about it (no extra allow rules). This is up to the user, if they don't want anything leaving their machine they'll have to manage these rules explicitly.

- Improve error message if handle is 0 (= not found or hasn't been refreshed)
- Add debug logging when route rules are added
- Replace nftables userdata (rule ID) with a rule hash

Refactor firewall manager check ( #2054 )

Some systems don't play nice with a test chain
So we dropped the idea, and instead we check for the filter table
With this check, we might face a case where iptables is selected once and on the
next netbird up/down it will go back to using nftables
