PERF: applies optimisations on chat-live pane (#20532) 

- group writes when computing separators positions
- shows skeleton only on initial load
- forces date separator to be pinned when first message to prevent a pinned - not pinned - pinned sequence when loading more in past
- relies on `message.visible` property instead of checking `isElementInViewport`
- attempts to load next/prev messages earlier
- do not scroll to on fetch more
- hides `last visit` text while pinned
