refactor(components): replace items prop in Navbar component

* replace `items` prop with `children` prop: it is more readable this
way,
* handle navbar item state inside NavbarItem component: it avoid using
three differents states and their methods to do exactly the same thing
* remove useAutofocus hook since we can't use it anymore
* add `onActivation` and `activationHandlerDelay` prop to NavbarItem
component to be able to focus the search input only when the item is
activated (it replicates the functioning of useAutofocus hook)
* replace `ref` type in SearchForm component: it does not make sense to
use an input ref for a form. Instead I use useImperativeHandle to
provide different a focus method to the given ref.
