This makes all the regular WebGPU object creation handle errors properly
in the Vulkan backend instead of ASSERTing no Vulkan error is raised.
Static Create functions are added to all these types so that the details
of how the initialization is done is private, and it isn't possible to
construct an object but forget to initialize it.

The dawn.h and dawncpp.h structure definitions references dawnFoo or
dawn::Foo respectively when it should reference dawn_native::FooBase* in
dawn_native. Autogenerate files to declare the dawn_native version of
the structs and change the ProcTable generation to use it instead.
This is important to make libdawn_native a shared library because
currently it was depending on dawncpp's definition of .Get().
