Analytics - Port event reference to github

https://developer.adobe.com/client-sdks/documentation/adobe-analytics/event-reference/#events-handled-by-analytics

Keep only the general event information in sdkdocs - internal events for Adobe Analytics

Start with the linked Adobe Analytics event-reference page and compare it with the relevant content in sdkdocs. Port only the general event information, excluding internal Adobe Analytics events; done means the GitHub documentation contains the general reference and omits those internal events.
