Refactor: Extract common code from LaunchRequestHandler's delegate

See ILaunchDelegate.java#L25-L27

    CompletableFuture<Response> launchInTerminal(LaunchArguments launchArguments, Response response, IDebugAdapterContext context);

    CompletableFuture<Response> launchInternally(LaunchArguments launchArguments, Response response, IDebugAdapterContext context);

There is common logic in implementation for both interfaces. The main differences in implementation for debug/noDebug are:

• launchInTerminal: It constructs different command string, and then take different actions according to response.
• launchInternally: It starts debuggee process in different ways.

Refactor work should be done to make code clean and readable.

Comece por ILaunchDelegate.java nas linhas 25-27 e, em seguida, inspecione as implementações de launchInTerminal e launchInternally no delegate de LaunchRequestHandler. Compare a lógica compartilhada e as diferenças de debug/noDebug descritas na issue; considera-se concluído quando o comportamento comum estiver consolidado e o delegate continuar legível sem alterar esses comportamentos distintos de lançamento.
