Upgrade polkadot-sdk to version 1.7.0

[RomarQ]

What does it do?

This PR updates polkadot-sdk dependencies to version 1.7.2.

• cherry-pick changes included in polkadot-v1.7.1 release
• cherry-pick changes included in polkadot-v1.7.2 release

What important points reviewers should know?

Polkadot-sdk version 1.7.0 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
