check sampler type in as_bind_group derives (#12637)
# Objective

currently if we use an image with the wrong sampler type in a material,
wgpu panics with an invalid texture format. turn this into a warning and
fail more gracefully.

## Solution

the expected sampler type is specified in the AsBindGroup derive, so we
can just check the image sampler is what it should be.

i am not totally sure about the mapping of image sampler type to
#[sampler(type)], i assumed:

```
    "filtering" => [ TextureSampleType::Float { filterable: true } ],
    "non_filtering" => [
        TextureSampleType::Float { filterable: false },
        TextureSampleType::Sint,
        TextureSampleType::Uint,
    ],
    "comparison" => [ TextureSampleType::Depth ],
```
