Whenever possible, `GPU.requestAdapter` and `GPUAdapter.requestDevice` should return a `GPUAdapter` and `GPUDevice` referring to the same platform adapter and device that WebRender is using.

This will help with bug 1814222 (avoiding CPU readback), since the pixels will already be on the right GPU.

Whenever possible, `GPU.requestAdapter` and `GPUAdapter.requestDevice` should return a `GPUAdapter` and `GPUDevice` referring to the same platform DXGI adapter that WebRender is using.

This will help with bug 1814222 (avoiding CPU readback), since the pixels will already be on the right GPU.

[edit: this used to imply that WebRender and WebGPU needed to be using the same device. This doesn't seem to be necessary: they just need to be on the same adapter.]
