This change adds delete, clear, serialize, parse, copy_from, and merge_from operations to the runtime. Since these operations can all be implemented easily on the `MessageLite` interface, we can use a common implementation in the runtime instead of generating per-message thunks for all of these. I suspect this will also make it possible to remove some of our generated trait implementations and replace them with blanket implementations, but I will leave that for a future change.
