update wgpu to 0.17 (#378)

required changes are entirely trivial:
wgpu::util::initialize_adapter_from_env's signature changed;
the backend_bits parameter is removed, and now solely specified by
the instance's enabled backends (see [the changelog](https://github.com/gfx-rs/wgpu/blob/trunk/CHANGELOG.md#initialize_adapter_from_env-argument-changes)).
