Tests + backport fix for teleport_assets (ReceiveTeleportedAsset) (#2235) (#2238)

* Wwstmint test for ReceiveTeleportedAsset

* Missing fix for `weigh_multi_assets`

* Added tests for statemine/statemint

* [Enhancement] Use XCM V3 for initiate_teleport weight calc (#2102)

* [Enhancement] Use XCM V3 for initiate_teleport weight calc

* deref

* replicate in all the runtimes

* fmt

* better handling for AllOf

* fmt

* small type fix

* replicate the fix for all runtimes

---------

Co-authored-by: parity-processbot <>

* removed `frame_support::sp_tracing::try_init_simple();`

* Review fixes

* Removed `as u64`
