Aurora's own debug groups only exist when AURORA_GFX_DEBUG_GROUPS is
defined, but the three ImGui passes (desktop overlay, host-frame overlay
and the headset settings panel) pushed and popped theirs in every build.
An Adreno 740 Android driver (512.676) faults in
vkCmdEndDebugUtilsLabelEXT on the first overlay pass (KartPad #321); the
Quest 3 uses the same GPU. Gate all three like the rest of Aurora.
Ported from chrissotraidis/wiicompiled (KartPad) 420b828, extended to the
two extra passes this fork has.

When no backend could create a window and a WebGPU device, aurora hit
an ASSERT and the process aborted with only SDL's last error in the log.
Keep the first adapter, device or window error, return it from
aurora_initialize with a new initializationStatus, and have the runtime
throw it so the existing fatal popup and fatal log record the reason.
ImGui shutdown now skips backends that never initialized, so the
shutdown that follows a failed start does not crash.
From upstream patchzyy/Wiicompiled 6f14bde (#244, KartPad batch).

The panel was drawn into the eye images, so below a 1.00x OpenXR
resolution its 1440x1080 canvas was minified into a small eye region and
the text became hard to read. It is now submitted as a quad layer of its
own over the scene's projection or menu quad, which the compositor samples
directly at any render scale.
Each backend (D3D12, Windows Vulkan, Quest) makes the panel's swapchain
pair (plus two shared buffers on the Quest) the first time the panel
opens. While it is open, the frame hands Aurora one more stereo target
after the eyes, which the bridge fills with the panel texture or a
transparent image. The panel image follows the eyes' displayed/retained
pairing, so a cancelled frame never shows an unwritten panel. The quad
hangs where the pointer's hits are tested. Aurora leaves the panel out of
the eyes in layer mode, and a backend that cannot make the layer falls
back to drawing it into the eyes.
On the Quest, debug.wiicompiled.panel_layer 0 selects the old path at
run time. Measured there at a race start (render_scale 0.8), the layer
costs nothing while the panel is closed; while it is open, app GPU time is
10.5 ms against 9.7 ms drawn into the eyes, with unchanged frame rates.
The replay tests cover lazy creation, cancelled frames, closed and
unplaced panels, and render-first pacing on D3D12 and Windows Vulkan.

- Introduced a new GX thread to handle the rendering pipeline, allowing the game thread to post commands without blocking.
- Added `gx_thread.h` and `gx_thread.cpp` to manage the command ring buffer and thread synchronization.
- Updated `vi.cpp` to utilize the GX thread for rendering tasks, improving frame pacing and responsiveness.
- Modified `main.cpp` to configure and start the GX thread, ensuring it integrates with the existing rendering workflow.
- Enhanced `openxr_integration.cpp` to register the GX thread with OpenXR for better performance in VR scenarios.
- Refactored `settings_overlay.cpp` to remove unnecessary waits for the frame worker, as the overlay now draws directly into the game thread's ImGui frame.
- Improved error handling and logging in the GX thread to capture exceptions during command execution.
