Bridges lane id agnostic for backwards compatibility

[bkontur]

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.

Important

• added migration for pallet_bridge_relayers and RewardsAccountParams change order of params, which generates different accounts

Deployment follow ups

• 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

Looks good as far as I can understand. I just left a couple of comments, mostly very small.

I hope I didn't miss anything. But please, in the future let's avoid this kind of big PRs since they are very hard to review. Let's try to split them. For this one in particular I would have had at least 2-3 PRs:

• the LaneID changes
• instantiating the Relayer rewards pallet
• any other changes
  And in each PR I would split the important changes from the non-important verbose ones (renamings, adding a generic parameter, etc)
