Bridges lane id agnostic for backwards compatibility (#5649)

This PR primarily fixes the issue with
`zombienet-bridges-0001-asset-transfer-works` (see:
https://gitlab.parity.io/parity/mirrors/polkadot-sdk/-/jobs/7404903).

The PR looks large, but most of the changes involve splitting `LaneId`
into `LegacyLaneId` and `HashedLaneId`. All pallets now use `LaneId` as
a generic parameter.

The actual bridging pallets are now backward compatible and work with
actual **substrate-relay v1.6.10**, which does not even known anything
about permissionless lanes or the new pallet changes.

- [x] added migration for `pallet_bridge_relayers` and
`RewardsAccountParams` change order of params, which generates different
accounts

- [ ] fix monitoring for
`at_{}_relay_{}_reward_for_msgs_from_{}_on_lane_{}`
- [ ] check sovereign reward accounts - because of changed
`RewardsAccountParams`
- [ ] deploy another messages instances for permissionless lanes - on
BHs or AHs?
- [ ] return back `open_and_close_bridge_works` for another
`pallet-bridge-messages` instance
