- Removes `native_menu.h` dependency from `display_server.h`.
It's now forward-declared in all DisplayServer implementations and should
be included in the .cpp's.
- Removes some unused `rb_set.h` and `rb_map.h` dependencies, which leads to
having to include them explicitly in half the scene and editor codebase...
which shows how much we depend on `display_server.h`.
- Forward-declare `input_event.h`, so now we need only `keyboard.h`.
G-SYNC (NVIDIA's VRR) is known to be buggy on windowed mode in Windows.
While the driver only enables G-SYNC for full screen mode by default,
users can toggle it on for windowed mode too, resulting in unstable
refresh rates during Editor usage.
This patch extends Godot's NVIDIA profile to force the default full
screen mode only G-SYNC with Godot.
