Bridges testing improvements (#6536)

This PR includes: - Refactored integrity tests to support standalone deployment of `pallet-bridge-messages`. - Refactored the `open_and_close_bridge_works` test case to support multiple scenarios, such as: 1. A local chain opening a bridge. 2. Sibling parachains opening a bridge. 3. The relay chain opening a bridge. - Previously, we added instance support for `pallet-bridge-relayer` but overlooked updating the `DeliveryConfirmationPaymentsAdapter`. --------- Co-authored-by: GitHub Action <[email protected]>
