Xamarin.forms: [CollectionView] Add ability to disable item animations

[adrianknight89]

Summary

Currently, if an item is added to CollectionView, the item is animated into its parent. There should be a way for us to toggle animations on and off. This could be achieved by setting ItemAnimator to null on RecyclerView (or configuring its properties) and using UIView.performWithoutAnimation during UICollectionView reloads.

API Changes

public bool ItemChangeAnimationsEnabled {get; set;} = true;
// bindable property for ItemChangeAnimationsEnabled

EDIT: Changed proposed property name.

Is there any progress?

Could be a 5.0.0 candidate?
