Add "insertAll" method to AnimatedList  #66609

Description

@nateshmbhat

When i'm using the AnimatedList widget, there are many times where i need to insert more than one time at a time.
Just like a normal list provides an insertAll method, the AnimatedList widget should also have an insertAll method that inserts multiple items.

    I'd like to extend the issue and ask for removeAll, and add an optional bool parameter when using either insertAll or removeAll to sync the animations of the inserted/removed items, so that they all get added at once (if possible).
