[testnet bridge] Permissionless dedicated bridge lanes deployment

[bkontur]

Description

The permissionless lanes feature was introduced here, but we want to deploy it on the testnet first.

Since Rococo is shut down, for testnet deployments we will initially use zombienet for end-to-end (e2e) tests, and then proceed with this issue.

Progress

• add drop_threashold support for congestion
• use HRMP suspend/resume or revert report_bridge_status (but then we need to add source chain router's pallet_instance for congestion - add new extrinsic report_bridge_congestion_to(origin, bridged_universal_location, Option<pallet_instance>) extrinsic + adding this option attirbute to the Bridge struct should be just a patch solution)
• for bridge messages pallet on AHs (instead of BHs), implement Investigation of deploying pallet-bridge-messages on the source/destination chain (without finality pallets) a.k.a. sync finality proofs service #5827
• add emulated tests: Bridge Permissionless Lanes - more tests #5552 (which could be reused for fellows)
• add zombienet tests Bridges testing improvements #5709
  • which will be reused for P/K bridge: [P<>K bridge] Permissionless dedicated bridge lanes polkadot-fellows/runtimes#476
