add: support host_discovery_ipv6 alive test for openvasd

Add `host_discovery_ipv6` as a new alive test bit for openvasd scans.

When `host_discovery_ipv6` is selected, it has priority over other alive test methods. The value is passed to gvm-libs through the new openvasd alive test methods struct.

This keeps the gvmd openvasd scan setup aligned with the new openvasd target API.
