Summary:
## Impact
Fix the Static ViewConfig for <View/>.
This diff fixes the base ViewConfig for all HostComponents on both platforms. Consequently, it simplifies SVC reconciliation efforts, by nearly eliminating the first of these classes of SVC errors:
1. Unexpected properties in SVC
2. Missing properties in SVC
3. Not matching properites in SVC
## What is the base ViewConfig on each iOS/Android?
**On iOS:**
- All props come from ViewManagers
- All HostComponent ViewManagers extend <View/> ViewManager

Therefore, the base ViewConfig for all components should be <View/>'s static ViewConfig.
**On Android:**
The component model is a bit more complicated:
https://pxl.cl/1Vmp5
Takeaways:
- Props come from Shadow Nodes **and** ViewManagers
- Nearly all HostComponent ViewManagers extend BaseViewManager. But, that's not <View/>'s ViewManager.
- <View/>'s ViewManager is [ReactViewManager](https://fburl.com/code/0zalv8zk), which is a descendent of BaseViewManager, and declares its own ReactProps.
So, on Android, it's not safe for the base ViewConfig to be <View>'s ViewConfig:
1. No components actualy incorportate <View/>'s props
2. Some components don't even incorporate BaseViewManager's props.
So, what should the base ViewConfig be on Android?
- Nearly all components extend BaseViewManager. BaseViewManager must have a shadow node [that extends LayoutShadowNode](https://www.internalfb.com/code/fbsource/[47d68ebc06e64d97da9d069f1ab662b392f0df8a]/xplat/js/react-native-github/ReactAndroid/src/main/java/com/facebook/react/uimanager/BaseViewManager.java?lines=40). Therefore, we'll make the base ViewConfig on Android be generated by BaseViewManager + LayoutShadowNode.
## Changes
In this diff, I removed ReactNativeViewViewConfig, and introduced a new view config called PlatformBaseViewConfig. This ViewConfig partial will capture all the props available on all HostComponents on **both** platforms. This may not necessarily be the props made available on <View/>.
The only components that don't extend the base platform props are: RCTTextInlineImage. What we do with these components is TBD.
