Add tests for the usage field of GPUTextureViewDescriptor

[vonture]

Added to the WebGPU spec in https://github.com/gpuweb/gpuweb/pull/4746. We need tests of:

• [ ] Validation of texture view usage in render pass outputs
• [ ] Validation of texture view usage in bind group entries
• [ ] Validation of compatible usage between the source texture and view
• [ ] Validation of inherited usage
• [ ] Drawing correctness tests when using view usage that differs from source texture usage (minimal and inherited usages)
