Subject: [PATCH] [pallet-message-queue] Implement impl_trait_for_tuples for
 QueuePausedQuery (#2227)

These changes are required so that the bridgehub system runtimes can
more easily be configured with multiple message processors

Example usage:

```rust
use frame_support::traits::QueuePausedQuery;

impl pallet_message_queue::Config for Runtime {
    type QueuePausedQuery = (A, B, C)
}
