Store last submitted TextureId in PresentationData for getting front buffer snapshot. WebGPUParent::RecvQueueSubmit() stores the latest TextureId in the swap chain in PresentationData::LastSubmittedTextureId. To do so, it retrieves the OwnerId from ExternalTexture. Next, get PresentationData from OwnerId. If readback is required, it is performed synchronously. Its implementation is borrowed from WebGPUParent::RecvSwapChainPresent().
