Backport patch for xcm fungible benchmarks required by new FungibleAdapter (#3417)

We replaced deprecated `CurrencyAdapter`
[here](https://github.com/paritytech/polkadot-sdk/pull/3287) and we also
did the same for fellows
[here](https://github.com/polkadot-fellows/runtimes/pull/187/commits/2d6d3ac530d00f3d7a2495ad24ec286d06113125),
but this change requires this patch for xcm benchmarks.

Expected patch for  `pallet-xcm-benchmarks` as `8.0.1`
