Implement XcmPaymentApi and DryRunApi on all system parachains (p…

…aritytech#4634) Depends on paritytech#4621. Implemented the [`XcmPaymentApi`](paritytech#3607) and [`DryRunApi`](paritytech#3872) on all system parachains. More scenarios can be tested on both rococo and westend if all system parachains implement this APIs. The objective is for all XCM-enabled runtimes to implement them. After demonstrating fee estimation in a UI on the testnets, come the fellowship runtimes. Step towards paritytech#690.
