fix: correct ddcci config structure

1. Moved the "global" property into the "flags" array for both
supportDdcci and isBacklightHelperHold settings
2. Removed the standalone "global": true key to comply with the correct
DSG config schema
3. This ensures the configuration is properly parsed and applied
globally as intended

Log: Fixed DDC/CI brightness configuration format to ensure proper
global application

Influence:
1. Verify that DDC/CI brightness control is correctly recognized as a
global setting in the system configuration
2. Test adjusting external monitor brightness to ensure DDC/CI support
is enabled as expected
3. Check if the backlight helper process hold setting is correctly
applied globally

fix: 更正ddcci配置结构

1. 将 supportDdcci 和 isBacklightHelperHold 设置项的 global 属性移至
flags 数组中
2. 移除了独立的 global: true 键，以符合正确的 DSG 配置架构规范
3. 这确保了配置能被正确解析，并按预期全局生效

Log: 修复DDC/CI亮度配置格式，确保其正确全局生效

Influence:
1. 验证 DDC/CI 亮度控制是否在系统配置中被正确识别为全局设置
2. 测试调节外接显示器亮度，确保 DDC/CI 支持按预期启用
3. 检查亮度调节驻留设置是否正确全局应用
