fuzzing: Add error injection macros to the Vulkan backend

This will enable fuzzing the Vulkan backend with randomly injected
errors to help ensure the backend properly handles all errors. It also
redefines VkResult in the dawn_native::vulkan namespace such that a
VkResult cannot be used unless it is explicitly wrapped.
