DisplayServer.get_display_safe_area() wrongly accounts for taskbar on Windows, even on fullscreen mode

Tested versions

• Reproducible in: 4.3.stable, 4.4.dev5

System information

Windows 10.0.19045 - Multi-window, 1 monitor - Vulkan (Forward+) - dedicated GeForce GTX 765M - Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz (8 threads)

Issue description

On a Windows 10 laptop with a 1920x1080 pixel screen with NO notches/cutouts, both DisplayServer.get_display_safe_area() and DisplayServer.screen_get_usable_rect() report a usable height of only 1040 pixels.

This seems to suggest that the Windows taskbar is being accounted for (it is exactly 40 pixels), which is neither useful nor a true account of the screen's safe area, especially for a fullscreen application. Running the application in windowed mode, fullscreen mode or exclusive fullscreen mode makes no difference to the reported value.

Steps to reproduce

Import the MRP and run the example scene.
Verify that toggling between exclusive fullscreen mode and windowed mode (with the "T" key) does not change the reported safe_area / usable_rect values.

Just confirmed that the issue persists on Windows 11. In a laptop with a 1920x1080 pixel screen (no notches/cutouts), Godot reports a "safe" height of 1020 pixels (the taskbar is 60 pixels high).
