The OpenGL backend can't gather discover default adapters because it needs getProc to do anything so we add DiscoverAdapters method to Instance that takes backend-specific options. dawn_native::opengl::CreateDevice is removed in favor of the adapter path so OpenGLBinding is modified to create an instance locally. This is only temporary until all backends support adapters, at which point a lot of *Binding code will be factored. Also contains a small fix for Result<T, E> with movable types.
