fbbb0b0ae0 gpu: use Dawn adapter creation API for now so that GPU_BACKEND selection works 
`webgpu.h` does not expose a method of choosing the GPU backend (vulkan, opengl, opengles, etc.)
at present. The only way to achieve this is to use Dawn's C++ API, which we expose as C shims
under the `machDawnNative*` prefix.

For now, we will use the Dawn adapter creation API so that we can choose between Vulkan/OpenGL/OpenGLES
etc via the `GPU_BACKEND` env var.

In the future, I believe we can do something nicer here. For example, perhaps we extend our `requestAdapter`
method (after all, we do not need to strictly match `webgpu.h`) to take such an option and be Dawn-aware so
that it handles this more seamlessly behind the scenes.
