zhouge941 87c2e8566f feat(camera): add USB camera VID/PID filtering via uevent
Implement USB camera device filtering using uevent PRODUCT field,
avoiding sysfs file access and SELinux permission issues.

Key features:
- Dual-layer filtering: uevent in CheckBuf + sysfs in V4L2UvcMatchDev
- USB interface → PRODUCT mapping for uevent processing
- Static thread-safe helper functions for uevent parsing
- System parameter config: const.camera.setting.usb_device_filter.config
