Remove `PROCESS_NAME_NATIVE` dwFlag in process query output

The `process_path` rule of sing-box is inherited from Clash,
the original code uses the local system's path format (e.g. `\Device\HarddiskVolume1\folder\program.exe`),
but when the device has multiple disks, the HarddiskVolume serial number is not stable.

This change make QueryFullProcessImageNameW output a Win32 path (such as `C:\folder\program.exe`),
which will disrupt the existing `process_path` use cases in Windows.

+### 对 Windows 上 `process_path` 格式的更新

+sing-box 的 `process_path` 规则继承自Clash，
