[bridges-v2] Permissionless lanes (#4949)

Relates to:
https://github.com/paritytech/parity-bridges-common/issues/2451
Closes: https://github.com/paritytech/parity-bridges-common/issues/2500

## Summary

Now, the bridging pallet supports only static lanes, which means lanes
that are hard-coded in the runtime files. This PR fixes that and adds
support for dynamic, also known as permissionless, lanes. This means
that allowed origins (relay chain, sibling parachains) can open and
close bridges (through BridgeHubs) with another bridged (substrate-like)
consensus using just `xcm::Transact` and `OriginKind::Xcm`.

_This PR is based on the migrated code from the Bridges V2
[branch](https://github.com/paritytech/polkadot-sdk/pull/4427) from the
old `parity-bridges-common`
[repo](https://github.com/paritytech/parity-bridges-common/tree/bridges-v2)._

## Explanation

Please read
[bridges/modules/xcm-bridge-hub/src/lib.rs](https://github.com/paritytech/polkadot-sdk/blob/149b0ac2

/bridges/modules/xcm-bridge-hub/src/lib.rs#L17-L136)
to understand how managing bridges works. The basic concepts around
`BridgeId` and `LaneId` are also explained there.


## TODO

- [x] search and fix for comment: `// TODO:(bridges-v2) - most of that
stuff was introduced with free header execution:
https://github.com/paritytech/polkadot-sdk/pull/4102` - more info in the
comment
[bellow](https://github.com/paritytech/polkadot-sdk/pull/4427#issuecomment-2126625043)
- [x] TODO: there's only one impl of `EnsureOrigin<Success = Location>`

## TODO - not blocking review

**benchmarking:**
- [x] regenerate all relevant weights for BH/AH runtimes
- [ ] regenerate default weights for bridging pallets e.g.
`modules/messages/src/weights.rs`
- [ ] add benchmarks for `xcm-bridge-hub` pallet
https://github.com/paritytech/polkadot-sdk/issues/5550

**testing:**
- [ ] add xcm-emulator tests for Rococo/Penpal to Westend/Penpal with
full opening channel and sending/receiving `xcm::Transact`

**migrations:**
- [x] add migrations for BridgeHubRococo/Westend
https://github.com/paritytech/parity-bridges-common/issues/2794 (to be
reusable for P/K bridge)
  - [x] check also storage migration, if needed for pallets
  - [ ] migration for XCM type (optional)
  - [x] migration for static lanes to the dynamic (reuse for fellows)

**investigation:**
- [ ] revisit
https://github.com/paritytech/parity-bridges-common/issues/2380
- [ ] check congestion around `LocalXcmChannelManager` and
`OutboundLanesCongestedSignals` impls -
https://github.com/paritytech/polkadot-sdk/issues/5551
  - to be reusable for polkadot-fellows
- return `report_bridge_status` was remove, so we need to `XcmpQueue`
alternative?
