webgpu.h: Reserve 0 for "undefined" in enums, and match spec enum order

Also add some TODOs and fix some formatting.

There is some risk of breakage in other projects if they assumed
certain values would be used when they zero-initialized. In particular:
- AddressMode_Repeat
- BlendFactor_Zero
- BlendOperation_Add
- AlphaMode_Premultiplied
- CullMode_None
- VertexStepMode_Vertex
- MipmapFilterMode_Nearest
- StencilOperation_Keep
- TextureAspect_All

Not done yet:
- DeviceLostReason, because it also needs renaming work (bug 2139)
- Possibly removing any 0 values that aren't needed
- Adding new Undefined values that will need more code changes
