Description
This PR uncouples pallet-xcm's Config trait from frame-system's RuntimeCall and instead uses it's own RuntimeCall trait type, it also removes the trait requirement for it's RuntimeCall to be
IsType<<Self as frame_system::Config>::RuntimeCall>, meaning you can write custom types to be used for the XCM Transact instruction in a runtime that has pallet-xcm, which was previously not possible because of the hardcoded requirement imposed by pallet-xcm, which is not imposed by xcm-executor.This does not require any other changes to existing or future code, since all it does is make the trait requirements slightly less strict, maintaining compatibility but expanding it.
