File path for deployement.toml file getting null in windows

Description:
Steps to re-produce

1. Execute the ciphertool.bat -Dconfigure in the windows environment
2. Deployment path for the deployment.toml file getting null from the following code segment.

    public static String getDeploymentFilePath() {
        String configFilePath = System.getProperty(Constants.DEPLOYMENT_CONFIG_FILE_PATH);
        if (StringUtils.isEmpty(configFilePath)) {
            configFilePath = Paths.get(System.getProperty(Constants.CARBON_CONFIG_DIR_PATH),
                             Constants.DEPLOYMENT_TOML_FILE).toString();
        }
       return configFilePath;
    }

The system property is getting null and executing the default encryption flow.

Start by tracing getDeploymentFilePath and the Windows ciphertool.bat -Dconfigure flow shown in the issue. Check why the deployment configuration system property is null on Windows and verify the fallback path behavior. Done means the deployment.toml path is resolved correctly instead of entering the default encryption flow.
