Asset Conversion release to westmint (#2148)

* Dex and payment by dex in westmint * Wrap U256 type for now (to support required traits.) * cargo fmt * We can now use U256 * Rename PromotedBalance * name change * Updating the code to master. TODO: handle dust! * cargo fmt * Minimising changes and step towards getting benchmarks compiling (still a From<u32> bound in the pallet) * minimise diff * Update parachains/runtimes/assets/westmint/src/lib.rs Co-authored-by: Jegor Sidorenko <5252494+jsidorenko@users.noreply.github.com> * Update parachains/runtimes/assets/westmint/src/lib.rs Co-authored-by: Jegor Sidorenko <5252494+jsidorenko@users.noreply.github.com> * Update parachains/common/src/impls.rs Co-authored-by: Jegor Sidorenko <5252494+jsidorenko@users.noreply.github.com> * Fix benchmark build * Add in AssetConversionAPI * Handle dust * cargo fmt * Don't need to be explicit that it's AccountId32 * remove pool setup fee (Asset deposit fees are a sufficient anti-spam measure) * More natural way to specify native * cargo fmt * Update parachains/runtimes/assets/westmint/src/lib.rs * Additional required impls * either form of multilocation should be acceptable. * add call filter exclusion * Fix typo & try_convert now fails if native is converted * merge master fixup * Fix: HoldReason should be there. * Box MultiAssetId Otherwise it blows out the Call enum memory size. * cargo fmt * update lock file * add std feature, update lock file * need to turn on std on common * adding in westmint tests * WeightToFee must be from the destination chain. * cargo fmt * account for higher ED on westmint * type removed as not used * cargo fmt * remove unused import * minimising diff * import needed only with feature enabled * use multilocation contains * move the impls to separate file * simplify on conversion * simplify on reverse conversion also. * rename var * clippy * removed dead code * cargo fmt * Use pay by swap * review suggestions * cargo fmt * Update parachains/runtimes/assets/asset-hub-westend/src/lib.rs Co-authored-by: joe petrowski <25483142+joepetrowski@users.noreply.github.com> * add benchmarks for new assets pallet * revert common/src changes * need a concrete id * more fixes * lock --------- Co-authored-by: Jegor Sidorenko <5252494+jsidorenko@users.noreply.github.com> Co-authored-by: joepetrowski <joe@parity.io> Co-authored-by: joe petrowski <25483142+joepetrowski@users.noreply.github.com>
