[#7966]: Fix XCM Barrier Rejection Handling to Return Incomplete with Weight
This PR addresses an issue with the handling of message execution when blocked by the barrier. Instead of returning an Outcome::Error, we modify the behaviour to return Outcome::Incomplete, which includes the weight consumed up to the point of rejection and the error that caused the blockage.
This change ensures more accurate weight tracking during message execution, even when interrupted. It improves resource management and aligns the XCM executor’s behaviour with better error handling practices.
