Can't use .set on generated bind groups with wgpu::RenderBundleEncoder

[tgecho]

I'm using a wgpu::RenderBundleEncoder instead of wgpu::RenderPass, but the generated .set methods only take a wgpu::RenderPass. Both have equivalent .set_bind_group methods.

Since there's no way that I see to get at the inner wgpu::BindGroup, I also can't use .from_bindings.

There's a wgpu::util::RenderEncoder trait that covers both of these types, though it leaves out wgpu::ComputePass, which might be nice to also support?
