webgpu.h introduce a base struct for extension structures.

 struct WGPUChainedStruct {
     WGPUChainedStruct const * nextInChain;
     WGPUSType sType;
 };

And changes all the nextInChain to point to such structures. This adds
more type safety to extension structs and requires less casting to check
sTypes and friends.
