feat: add LogIdList to RaftMetrics and RaftDataMetrics behind metrics-logids feature flag

LogIdList tracks the last log ID per leader, which is useful for
deterministic testing to observe exact log state through metrics.
Since it is heap-allocated (Vec), it is gated behind a feature flag
to avoid overhead in production builds. The field uses serde(skip)
when both metrics-logids and serde features are active, because
LogIdList has no serde derives.

Changes:
- Add metrics-logids feature flag to openraft/Cargo.toml
- Add LogIdListOf<C> type alias in type_config::alias
- Add log_id_list field to RaftMetrics and RaftDataMetrics
- Populate log_id_list from st.log_ids in raft_core.rs
- Document the feature flag in feature-flags.md
- Add unit tests for the new field
