Valentin Shergin 62544c0830 Fabric: Proper traits for ImageShadowNode and ViewShadowNode
Summary:
* <Image> must be a leaf node; having a proper trait will fail earlier in case of misuse (mounting something inside).
* <View> must have a `View` trait because it's for what that trait is.

Changelog: [Internal] Fabric-specific internal change.

Valentin Shergin 14a174c237 Fabric: Implementation of ViewProps::zIndex feature in C++ core
Summary:
Now, having `orderIndex` feature in the core, we can use it for implementing `zIndex` feature. All we need to do is just to assign this `zIndex` value to `orderIndex`.
Then we will use this to remove some platform-specific code that implements `zIndex` on the mounting layer.

Valentin Shergin b5117bf6ea Fabric: New two ShadowNode Traits: FormsStackingContext & FormsView
Summary:
This diff introduces two new `ShadowNodeTrait`s that we will use in the future in the new (slightly tweaked) view-flattening algorithm. (Note: this diff does not enable the new flattening, it's just preparation.)
The idea is that we split the notion of `isLayoutOnlyView` into two traits:
* `FormsView`: `ShadowNode`s with this trait must be represented as `ShadowView`s. Normal "visible" ShadowNodes will have this trait, but "layout only views" in old nomenclature will not.
* `FormsStackingContext`: `ShadowNode`s with this thread not only must be represented as `ShadowView`s but also have to form a "stacking context" which means that their children must be mounted as `ShadowView`'s children.

Our implementation does not exactly follow W3C spec in terms of sets of props that create the stacking context (because of historical reasons and mobile specifics) but ideologically it's the same. We start from the very conservative implementation where only views with background-color and borders do not form stacking context and then we probably extend that to more props.

Most importantly for us now, we will enforce the absence of ``FormsStackingContext` for `ParagraphShadowNode` and the presence of `FormsView` for `TextShadowNode` on Android where it's essential for mounting layer.

Summary:
All code styles are terribly ugly. We have the only choise - choise something and embrace it.
This particular code style was borrowed from a neibour Fabric-friendly project because it follows established Facebook guides and respects client-side traditions.

Valentin Shergin 67a79010ca Fabric: Simplified way to specialize ComponentName in ConcreteShadowNode class template
Summary:
@public
Previously, all ConcreteShadowNode subclasses had to override `getComponentName()` function to specialize a name of the component. And often it was all that those subclasses do. Now, it's a template argument; and many ShadowNode classes can be created as oneliners via *just* specializing  ConcreteShadowNode template.

Unfortunately, C++ does not allow to use `std::string`s or string literals as template arguments, but it allows to use pointers. Moreover, those pointers must point to some linked data, hence, those values must be declared in .cpp (not .h) files. For simplicity, we put those constants in Props classes, (but this is not a strong requirement).
