girazoki 9a04ebbfb0 [pallet-xcm] fix transport fees for remote reserve transfers (#3792 )

Currently `transfer_assets` from pallet-xcm covers 4 main different
transfer types:
- `localReserve`
- `DestinationReserve`
- `Teleport`
- `RemoteReserve`

For the first three, the local execution and the remote message sending
are separated, and fees are deducted in pallet-xcm itself:
https://github.com/paritytech/polkadot-sdk/blob/3410dfb3929462da88be2da813f121d8b1cf46b3/polkadot/xcm/pallet-xcm/src/lib.rs#L1758.

For the 4th case `RemoteReserve`, pallet-xcm is still relying on the
xcm-executor itself to send the message (through the
`initiateReserveWithdraw` instruction). In this case, if delivery fees
need to be charged, it is not possible to do so because the
`jit_withdraw` mode has not being set.

This PR proposes to still use the `initiateReserveWithdraw` but
prepending a `setFeesMode { jit_withdraw: true }` to make sure delivery
fees can be paid.

A test-case is also added to present the aforementioned case

Assets Parachain

Implementation of Asset Hub, a blockchain to support generic assets in the Polkadot and Kusama networks. Asset Hub was formerly known as "Statemint".

Asset Hub allows users to:

Deploy promise-backed assets, both fungible and non-fungible, with a DOT/KSM deposit.
Set admin roles to manage assets and asset classes.
Register assets as "self-sufficient" if the Relay Chain agrees, i.e. gain the ability for an asset to justify the existence of accounts sans DOT/KSM.
Pay transaction fees using sufficient assets.
Transfer (and approve transfer) assets.
Interact with the chain via its transactional API or XCM.

Asset Hub must stay fully aligned with the Relay Chain it is connected to. As such, it will accept the Relay Chain's governance origins as its own.

See the article on Asset Hub as common good parachain for a higher level description.

Wallets, custodians, etc. should see the Polkadot Wiki's Integration Guide for details about support.
