XCM V5 - SetHints instruction (paritytech#6566)

Last feature we wanted for V5, changing `SetAssetClaimer` to be just one of many possible "hints" that you can specify at the beginning of your program to change its behaviour. This makes it easier to add new hints in the future and have barriers accept them. --------- Co-authored-by: GitHub Action <[email protected]>
