zx::result<uint32_t> Create2DResource (uint32_t width, uint32_t height, display::PixelFormat pixel_format)

Creates a 2D resource on the virtio host.

Returns the allocated resource ID. The returned ID is guaranteed to not

have been used for another active resource.

This API does not currently support releasing resources, so every allocated

resource remains active for the driver's lifetime. However, the underlying

virtio spec does support releasing resources, via a

VIRTIO_GPU_CMD_RESOURCE_UNREF operation. So, this API may support releasing

resources in the future.
