stream_popover: Add "Rename topic" option in topic sidebar popover.

This commit adds "Rename topic" option in topic sidebar popover
which will be shown when user is only allowed to edit topics and
not streams.

Note that we still cannot show or hide the option as per the time
limit setting (since client may not have the first message of the
topic locally), so we just show or hide it as per
move_messages_within_stream_policy setting.

Fixes #19886.
