[Feature Request] Add support for dashboard overlays

[CrispyPin]

I am making an overlay app, and in terms of settings and menus I'm restricted to putting it in a regular overlay or on the desktop window. It would make sense to have some settings available from the dashboard, especially meta things like controller bindings.

Yes, I would like to add that feature, but not sure if it will come here to the Godot OpenVR plugin, or if we'll switch everything over with the OpenXR plugin.

Has this feature been completed?
Can OpenXR achieve the dashboard functionality? I didn't see any relevant dashboard interfaces in OpenXR.

是的，我想添加该功能，但不确定它是否会出现在 Godot OpenVR 插件中，或者我们是否会使用 OpenXR 插件来切换所有内容。

There is an OpenXR extension for overlays, XR_EXTX_overlay, but I don't think SteamVR implements it yet, so nobody is making anything with it. I'm not sure if other OpenXR runtimes like Monado support it.

It seems like you can use this to run OpenXR overlays in SteamVR but i have not tried it, and GodotVR/godot_openxr doesn't mention anything about XR_XTX_overlay.

有一个 OpenXR 叠加扩展 XR_EXTX_overlay，但我认为 SteamVR 还没有实现它，所以没有人用它做任何事情。我不确定 Monado 等其他 OpenXR 运行时是否支持它。

https://steamcommunity.com/app/250820/discussions/8/2448217320142811491/ https://github.com/LunarG/OpenXR-OverlayLayer 似乎你可以使用它在SteamVR中运行OpenXR叠加层，但我还没有尝试过，并且GodotVR/godot_openxr没有提及任何有关 XR_XTX_overlay 的内容。

I agree with your viewpoint. It can be confirmed that SteamVR has not been implemented OpenXR's overlay.
