[ivette] Several fixes

- The `useSelection` hooks did not memoized the returned `setSelection`
  function, leading to performance issues if a hook depended on it.

- The standard behavior for `usePromise` is to take a building function
  and dependencies, automatically memoized the constructed promise, and
  then doing as before. However, we keep a `usePromiseNoMemo` with the
  previous behavior. It seems needed for the `theme` handling.

- `useCache` new hook allows to add a cache to a given function. It also
  takes an optional serialization function for complex types for which
  standard equality does not provide the expected behavior.
