instance.create_surface() panics

[thequver]

Description
Hello, i'm using wgpu 0.19.1 and my application panics on an old laptop when creating a surface with this error:
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', C:\Users\ACER\.cargo\registry\src\index.crates.io-6f17d22bba15001f\wgpu-core-0.19.0\src\instance.rs:521:39
This happens when i use wgpu::Backends::PRIMARY in the instance descriptor. If i use wgpu::Backends::SECONDARY everything works. I didn't have this error in wgpu 0.18, I think this is beause directx11 backend was removed. I seems my laptop was using it before because it doesn't support vulkan.

Repro steps
Unlikely you can reproduce this because the laptop is too old.

Expected vs observed behavior
instance.create_surface() panics but maybe you can return an error instead of just panic?

Platform
Win11, wgpu 0.19.1, ATI Mobility Radeon HD 5470 graphics card

The panic was fixed in

• Fix panic when creating a surface while no backend is available #5166

with that surface creation should return an error in your case
