This commit adds the useEffect hook, inspired by React. This hook replaces the onMounted, onWillPatch, onPatched and onWillUnmount hook. The idea behind useEffect is to unify the way we add side-effects to the components lifecycle, while also making it easier to clean up those side effects when needed. A lot of the time, when you want to do something once the component is mounted, there is also a good chance you would like to do it again when the component's state or props changes, in that case you may also want to clean up things that you did on the previous render. useEffect covers all these use cases and more. The API is like that of React, with an important difference: the dependencies of the effects is a function returning an array instead of a plain array. This is because in React, hooks will run on every render while in OWL, hooks are only run once during the component setup phase. This means that in React, dependencies are computed on every render, and doing that in owl requires having a callback to recompute them. Because computing your dependencies can be expensive, the dependencies computed by the callback will be passed to the effect function so that it doesn't have to recompute them. (In React, since you're writing in the render function, the dependencies are already in the effect's closure).
