ipnext,ipnlocal,wgengine/filter: add extension hooks for custom filter matchers
Add PacketMatch hooks to the packet filter, allowing extensions to
customize filtering decisions:

- IngressAllowHooks: checked in RunIn after pre() but before the
  standard runIn4/runIn6 match rules. Hooks can accept packets to
  destinations outside the local IP set. First match wins; the
  returned why string is used for logging.

- LinkLocalAllowHooks: checked inside pre() for both ingress and
  egress, providing exceptions to the default policy of dropping
  link-local unicast packets. First match wins. The GCP DNS address
  (169.254.169.254) is always allowed regardless of hooks.

PacketMatch returns (match bool, why string) to provide a log reason
consistent with the existing filter functions.

Hooks are registered via the new FilterHooks struct in ipnext.Hooks
and wired through to filter.Filter in LocalBackend.updateFilterLocked.
