Suppress some strict-aliasing related warnings in WebGPU EP (#23454)

### Description
Suppress some strict-aliasing related warnings in WebGPU EP

For example:
```
/home/chasun/src/onnxruntime/onnxruntime/core/providers/webgpu/math/unary_elementwise_ops.cc:208:30: error: dereferencing type-punned pointer will break strict-aliasing rules [-Werror=strict-aliasing]
  208 |       float encoded_value = *reinterpret_cast<const float*>(attr);
      |                              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```

This PR does not really fix the problems. It just suppresses the
warnings to make build pass. Some issues related to strict aliasing may
be fixed by using std::bit_cast, which requires c++20 however.


### Motivation and Context
Build the code on Azure Linux 3 fails. To reproduce the issue, you may
get an AzureLinux3 machine and run:
```
 python3 tools/ci_build/build.py --update --build  --build_wheel --use_xnnpack --build_nodejs   --use_webgpu --build_dir b --skip_submodule_sync --parallel --use_binskim_compliant_compile_flags --build_shared_lib --config Release
```
