XCM programs generated by the `InitiateAssetTransfer` instruction shall have the option to carry over the original origin all the way to the final destination. They shall do so by internally making use of `AliasOrigin` or `ClearOrigin` depending on given parameters. This allows asset transfers to retain their original origin even across multiple hops.

…structions The AllowTopLevelPaidExecutionFrom allows ClearOrigin instructions before the expected BuyExecution instruction, it also allows messages without any origin altering instructions. This commit enhances the barrier to also support messages that use AliasOrigin, or DescendOrigin. This is sometimes desired in asset transfer XCM programs that need to run the inbound assets instructions using the origin chain root origin, but then want to drop privileges for the rest of the program. Currently these programs drop privileges by clearing the origin completely, but that also unnecessarily limits the range of actions available to the rest of the program. Using DescendOrigin or AliasOrigin allows the sending chain to instruct the receiving chain what the deprivileged real origin is. See polkadot-fellows/RFCs#109 and polkadot-fellows/RFCs#122 for more details on how DescendOrigin and AliasOrigin could be used instead of ClearOrigin.
