core, core/vm: implemented a generic environment (#3348)
Environment is now a struct (not an interface). This reduces a lot of tech-debt throughout the codebase where a virtual machine environment had to be implemented in order to test or run it. The new environment is suitable to be used en the json tests, core consensus and light client.
