litep2p: Update litep2p to v0.8.0 (#6353)

This PR updates litep2p to the latest release.

- `KademliaEvent::PutRecordSucess` is renamed to fix word typo
- `KademliaEvent::GetProvidersSuccess` and
`KademliaEvent::IncomingProvider` are needed for bootnodes on DHT work
and will be utilized later


### Added

- kad: Providers part 8: unit, e2e, and `libp2p` conformance tests
([#258](paritytech/litep2p#258))
- kad: Providers part 7: better types and public API, public addresses &
known providers ([#246](paritytech/litep2p#246))
- kad: Providers part 6: stop providing
([#245](paritytech/litep2p#245))
- kad: Providers part 5: `GET_PROVIDERS` query
([#236](paritytech/litep2p#236))
- kad: Providers part 4: refresh local providers
([#235](paritytech/litep2p#235))
- kad: Providers part 3: publish provider records (start providing)
([#234](paritytech/litep2p#234))

### Changed

- transport_service: Improve connection stability by downgrading
connections on substream inactivity
([#260](paritytech/litep2p#260))
- transport: Abort canceled dial attempts for TCP, WebSocket and Quic
([#255](paritytech/litep2p#255))
- kad/executor: Add timeout for writting frames
([#277](paritytech/litep2p#277))
- kad: Avoid cloning the `KademliaMessage` and use reference for
`RoutingTable::closest`
([#233](paritytech/litep2p#233))
- peer_state: Robust state machine transitions
([#251](paritytech/litep2p#251))
- address_store: Improve address tracking and add eviction algorithm
([#250](paritytech/litep2p#250))
- kad: Remove unused serde cfg
([#262](paritytech/litep2p#262))
- req-resp: Refactor to move functionality to dedicated methods
([#244](paritytech/litep2p#244))
- transport_service: Improve logs and move code from tokio::select macro
([#254](paritytech/litep2p#254))

### Fixed

- tcp/websocket/quic: Fix cancel memory leak
([#272](paritytech/litep2p#272))
- transport: Fix pending dials memory leak
([#271](paritytech/litep2p#271))
- ping: Fix memory leak of unremoved `pending_opens`
([#274](paritytech/litep2p#274))
- identify: Fix memory leak of unused `pending_opens`
([#273](paritytech/litep2p#273))
- kad: Fix not retrieving local records
([#221](paritytech/litep2p#221))
