Serialize/Deserialize trait implemented in no-std for XCM assets (#3057)

Browse Source 
Continues the work of https://github.com/paritytech/polkadot/pull/7312.
`MultiLocation` was modified to implement serialize in no-std in that
PR, but not the assets types.
This PR does the same for assets, and this also allows to inject them in
pallets that require them in genesis.
