op2 issue with async getter in objects

[chirsz-ever]

Related deno issue: denoland/deno#28521

The GPUDevice.lost is implemented here:

https://github.com/denoland/deno/blob/2a01ac448273ffe3a4b2774598fab196a2269668/ext/webgpu/device.rs#L596C6-L607

But there is no lost getter on the device object actually created.
