Deprecate dmp-queue pallet (paritytech#4475)

`cumulus-pallet-dmp-queue` is not needed anymore since paritytech#1246. The only logic that remains in the pallet is a lazy migration in the [`on_idle`](https://github.com/paritytech/polkadot-sdk/blob/8d62c13b2541920c37fb9d9ca733fcce91e96573/cumulus/pallets/dmp-queue/src/lib.rs#L158) hook. --------- Signed-off-by: Oliver Tale-Yazdi <[email protected]>
