This PR introduces: - XCM host functions `xcm_send`, `xcm_execute` - An Xcm trait into the config. that proxy these functions to to `pallet_xcm`, or disable their usage by using `()`. - A mock_network and xcm_test files to test the newly added xcm-related functions. --------- Co-authored-by: Keith Yeung <kungfukeith11@gmail.com> Co-authored-by: Sasha Gryaznov <hi@agryaznov.com> Co-authored-by: command-bot <> Co-authored-by: Francisco Aguirre <franciscoaguirreperez@gmail.com> Co-authored-by: Alexander Theißen <alex.theissen@me.com>
