Dario Piotrowicz 8ba43a1a1e fix(animations): retain triggers values for moved tracked list items (#44578)
when reordering a list with animations the list items lose their current
triggers values, that is because the reordering of an item is implemented
as follows (_note:_ the following implementation has been added in PR #23534)
 - the item is removed and marked _setForRemoval_
 - the item is re-inserted, and the _setForRemoval_ is changed to _setForMove_
 - the player set for animating the removal is destroyed when _setForMove_ is detected

the above steps allow the element not to be animated and to keep its styling but the
triggers values get lost since the removal transition/player has already been initialized,
so this change adds a _previousTriggersValues_ map in the _REMOVAL_FLAG_ field in order to
restore the triggers values if/when the removal turns out to be a move, changing the above steps to:
 - the item is removed and marked setForRemoval __and its current triggers values are saved as well__
 - the item is re-inserted, and the setForRemoval is changed to setForMove
 - the player set for animating the removal is destroyed when setForMove is detected __and the
   trigger values are re-applied in the engine's statesByElement map__
