### Godot version

v4.0.3.stable.official [5222a99f5]

### System information

Windows 11, AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx     2.10 GHz

### Issue description

  The request_attention () function on Windows only flashes the taskbar, but what if the taskbar is hidden ?  In display_server_windows.cpp, FLASHW_TRAY is used, when it might be more appropriate to use FLASHW_ALL which flashes both the caption and the tray.

### Steps to reproduce
