Upgrade polkadot-sdk to version 1.7.2

[RomarQ]

What does it do?

This PR updates polkadot-sdk dependencies to version 1.7.2.

What important points reviewers should know?

Polkadot-sdk version 1.7.2 includes XCMv4, which removes the Multi prefix in many places, changes some XCM syntax (examples below) and removes Abstract variant from AssetId.

New syntax for building locations and junctions

Now junctions are built using the following methods:

let location = Location {
    parents: 1,
    interior: [Parachain(1000), PalletInstance(50), GeneralIndex(1984)].into()
};

or

let location = Location::new(1, [Parachain(1000), PalletInstance(50), GeneralIndex(1984)]);

And they are matched like so:

match location.unpack() {
  (1, [Parachain(id)]) => ...
  (0, Here) => ...,
  (1, [_]) => ...,
}

This syntax is mandatory in v4, and has been also implemented for v2 and v3 for easier migration.

This was needed to make all sizes smaller.

Removed Abstract asset id

Now assets are just constructed as follows:

let asset: Asset = (AssetId(Location::new(1, Here)), 100u128).into();
No need for specifying Concrete anymore.

Is there something left for follow-up PRs?

NO

Are there relevant PRs or issues in other repositories (Polkadot-sdk, Frontier)?

• cumulus-consensus-common: block import: delayed_best_block flag added paritytech/polkadot-sdk#2001

  This PR adds the delayed_best_block flag to ParachainBlockImport. If not set, the params.fork_choice is not updated (to ForkChoiceStrategy::Custom) during the block import.

  When delayed_best_block is set to false all parachain blocks on the longest fork will be notified as the best block, allowing transaction pool to be updated with every imported block.

  Otherwise imported blocks will not be notified as best blocks (fork_choice=ForkChoiceStrategy::Custom(false)), and transaction pool would be updated only with best block received from relay-chain.

• Adapt maintenance mode pallet to MessageQueue dmp/xcmp pause Moonsong-Labs/moonkit#25 (DmpQueue and XcmpQueue (partially))

What value does it bring to the blockchain users?
