spirv-val Validate OpSpecConstantOp

https://godbolt.org/z/dxh6WvG9Y

```
%data_grid = OpSpecConstantComposite %arr_v3uint_2 %inner_v0 %inner_v1
%extract_6 = OpSpecConstantOp %uint CompositeExtract %data_grid 3 2
```

@alan-baker I hit this today, it and spent to long figuring out what was wrong

I remember I tried to add https://github.com/KhronosGroup/SPIRV-Tools/pull/4907 before and we never got that, is there a way you propose to go about doing that PR, I forgot the details, but I think you didn't want a re-call of the pass
