[NUI] Introduce CollectionView and related classes. (#2525)

[NUI] Introduce CollectionView and related classes. (#2525)

* Introduce CollectionView and related classes.

View :
[ItemsView] Base class of model based view. create item by DataTemplate and
            layouting them with layouter using source data. inherited from ScrollableBase.
[CollectionView] groupable and selectable ItemsView.

Item :
[ViewItem] Base item for CollectionView.
[ViewItem.Internal] Internal partial class of ViewItem.
[ViewItemStyle] Style class of ViewItem.
[OneLineLinearItem] Linear type ViewItem of 1 line text Label and Icon, Extra View.
[OutLineGridItem] Grid type ViewItem of outline caption Label and ImageView Image and View Badge.

Layouter :
[ItemsLayouter] Base compositor class of item layouter on ItemsView.
[LinearLayouter] Layouter class of layouting item in linear list. restricted for CollectionView class only.
[GridLayouter] Layouter class of layouting item in grid list. restricted for CollectionView class only.

Item Source :
[ItemsSourceFactory] Factory of creating IItemSource from IEnumerable source.
[IItemSource] Interface for encapsulated data source from IEnumerable user source.
[IGroupedItemSource] Interface for grouped user data.
[EmptySource] Empty data source.
[ListSource] List data source.
[ObservableItemSource] Item source who provide observable notifications.
[ObservableGroupedSource] Grouped item source who provide observable notifications.
[UngroupedItemSource] Ungrouped item source.

Enum and Interface :
[ICollectionChangedNotifier] Interface of collection changed notifier.
[ItemSelectionMode] Mode enum value for Selection.
[ItemSizingStrategy] Sizing strategy for item measure.
[SelectionChangedEventArgs] Event for Selection changed notify.

Helper Class :
[MarshalingObservableCollection] Marshaling ObservableCollection for itemSource.
[SelectionList] Internal list for SelectionModel.

Other Changes :
Moving and change internal to public of DataTemplate related classes.

Known Issues :
- Empty items or pages shows when scroll fast, jump by ScrollTo().
- ScrollTo() is moving incorrectly.
- Scrolling event passing scrollPosition negative value.
- Application cannot initialize the cached ViewItem.
- Image trembling while scrolling.

Remaining Works :
- Implement groupable features.
- Implement observable changes(ICollectionChangedNotifier).
- Implement dynamic size and dynamic template selector.
- Implement Item / Layouter animations and support custom animations.
- Adding samples and test.
- Adding Unit Test.
- Documents and guides.

* [NUI] Update templates to EditorBrowsableState.Never

* [CollectionView] fix wrong initialize layouter and item count which makes missing 0 and last indexed item in Header/Footer exist

* [CollectionView] fix missing call of OnRelayout in base class.

* [CollectionView] Implement Groupable Features and Refactoring Items

1. Implement Groupable features in CollectionView, LinearLayouter,
    GridLayouter.
2. Refactoring items and adding styles.
   OneLineLinearItem => DefaultLinearItem : SubLabel added.
                                            Use RelativeLayout.
					    Apply DefaultLinerItemStyle.
   OutLineGridItem => DefaultGridItem : Label changed Caption.
                                        Use RelativeLayout.
					Support CaptionOrientation.
					Apply DefaultGridItemStyle.
   DefaultTitleItem is added for Header / GroupHeader.
3. Sample is udpated.
4. Remove _ in the code.

* [CollectionView] Refactoring class directories

- Move all item source related classes in ItemSource
- Move all item class in Item
- Move all layouter class in Layouter

* [NUI] add copy-right license pre-comments
