Introduce <RecordsIterator> - #10880

Problem

ListIterator has a drawback: empty, loading and error states appear inside the wrapper (often a <ul>). It makes it unusable in most cases.

Solution

• Replace ListIterator by RecordsIterator, with an alias to ListIterator
• Update <SimpleList>
• Update WithListContext to accept optional empty, loading, error and offline components
• Update ListBase / InfiniteListBase / EditBase / ShowBase and derivated components to accept optional authLoading, loading and error components.

Additional Checks

• The PR targets master for a bugfix or a documentation fix, or next for a feature
• The PR includes unit tests (if not possible, describe why)
• The PR includes one or several stories (if not possible, describe why)
• The documentation is up to date
