refactor(Notification): set notification portal from the components lifecycle: connectedCallback()

[dgonzalezr]

Description

This PR shifts the creation of the notification portal container from outside the component into the connectedCallback() lifecycle method. This change is necessary to support SSR #1216 and to prevent errors when calling the window or document object from the server, where they are not available.
