Disambiguate the associated function Into implementation not recognized and not automatically selected

[bitzoic]

#6857 introduces Into<Bytes> for a number of stack types. However, if the following syntax is used the compiler will not automatically recognize which Into implementation is the correct one.

let my_asset = AssetId::zero();
let my_bytes: Bytes = my_asset.into();

As a result, the following is required as a work around.

let my_asset = AssetId::zero();
let my_bytes: Bytes = <AssetId as Into<Bytes>>::into(my_asset);

The compiler should automatically determine which Into implementation is appropriate.
