refactor extra code, duplicates, complexity

- refactor array equality check and add tests
- remove OperatingSystem.Unknown causing extra logic, return undefined instead
- refactor enum validation to share same logic
- refactor scripting language factories to share same logic
- refactor too many args in runCodeAsync
- refactor ScriptCode constructor to reduce complexity
- fix writing useless write to member object since another property write always override it
