Trait to determine whether the execution engine should actually execute a given XCM.
Can be amalgamated into a tuple to have multiple trials. If any of the tuple elements returns Ok(), the

fn should_execute<RuntimeCall>( origin: &MultiLocation, message: &mut Xcm<RuntimeCall>, max_weight: Weight, weight_credit: &mut Weight ) -> Result<(), ()>
Returns true if the given message may be executed.
origin: The origin (sender) of the message.message: The message itself.max_weight: The (possibly over-) estimation of the weight of execution of the message.weight_credit: The pre-established amount of weight that the system has determined this message may utilize in its execution. Typically non-zero only because of prior fee payment, but could in principle be due to other factors.
