Use state transition bytecode from the database

[xgreenx]

Related issue https://github.com/FuelLabs/fuel-core/issues/1754

Updated the upgradable executor to fetch the state transition bytecode from the database when the version doesn't match a native one. This change enables the WASM executor in the "production" build and requires a wasm32-unknown-unknown target.

The executor has a VERSION constant that must be updated when the behavior of the state transition function is changed. That constant is used to decide what executor to use(WASM or native).
