networking: Update litep2p network backend to v0.9.4 (#8373)

# Litep2p Release

This release brings several improvements and fixes to litep2p, advancing
its stability and readiness for production use.

### Performance Improvements

This release addresses an issue where notification protocols failed to
exit on handle drop, lowering CPU usage in scenarios like
minimal-relay-chains from 7% to 0.1%.

### Robustness Improvements

- Kademlia:
- Optimized address store by sorting addresses based on dialing score,
bounding memory consumption and improving efficiency.
- Limited `FIND_NODE` responses to the replication factor, reducing data
stored in the routing table.
- Address store improvements enhance robustness against routing table
alterations.

- Identify Codec:
- Enhanced message decoding to manage malformed or unexpected messages
gracefully.

- Bitswap:
- Introduced a write timeout for sending frames, preventing protocol
hangs or delays.

### Testing and Reliability

- Fuzzing Harness: Added a fuzzing harness by SRLabs to uncover and
resolve potential issues, improving code robustness. Thanks to @R9295
for the contribution!

- Testing Enhancements: Improved notification state machine testing.
Thanks to Dominique (@Imod7) for the contribution!

### Dependency Management

- Updated all dependencies for stable feature flags (default and
"websocket") to their latest versions.

- Reorganized dependencies under specific feature flags, shrinking the
default feature set and avoiding exposure of outdated dependencies from
experimental features.
