Summary: Ports an internal ESLint rule used at Facebook, `error-subclass-name`, to cover the React Native codebase. This rule enforces that error classes ( = those with PascalCase names ending with `Error`) only extend other error classes, and that regular functions don't have names that could be mistaken for those of error classes.

Summary:
Some props must have their default values set by native. To be able to support this, we have to introduce a null as a supported default value for some types. In this diff I'm adding support for null default values for float props. An example of this to be useful is `ReactDrawerLayoutManager`:
```
Override
public void setDrawerWidth(ReactDrawerLayout view, Nullable Float width) {
int widthInPx =
width == null
? LayoutParams.MATCH_PARENT
: Math.round(PixelUtil.toPixelFromDIP(width));
view.setDrawerWidth(widthInPx);
}
```
We need to be able to generate an interface method, that accepts a boxed `Float` value instead of the primitive `float` so that the native code can decide what value to use by default (`LayoutParams.MATCH_PARENT` in this case).

Summary:
## Overview
This diff adds flow parser support for number unions as Int32Enums
The following will be supported as an Int32 enum:
```
interval?: WithDefault<0 | 15 | 30 | 60, 0>,
```
## Number type issues
We assume that all number enums are ints (so far there's not been a valid use case for unions of floats).
If we think there would be a use case for float unions we would need to update this to something like:
```
// Int32
intervalInt?: WithDefault<Int32Enum<0 | 15 | 30 | 60>, 0>,
// Float
intervalInt?: WithDefault<FloatEnum<0.0 | 15.1 | 30.2 | 60.3>, 0.0>,
```
My recommendation is that we default number unions to ints and if a use case arises later for floats, we would add the Float support as:
```
// Int32
intervalInt?: WithDefault<0 | 15 | 30 | 60, 0>,
// Float
intervalInt?: WithDefault<FloatEnum<0.0 | 15.1 | 30.2 | 60.3>, 0.0>,
```

Summary:
Our JS codegen assumes that all Android view managers extend `BaseViewManager` which allows generated delegates to set base view props using `BaseViewManagerDelegate`, see and example of the generated delegate for `FbReactTTRCStepRenderFlagManager`:
```
public class TTRCStepRenderFlagManagerDelegate<T extends View, U extends BaseViewManager<T, ? extends LayoutShadowNode> & TTRCStepRenderFlagManagerInterface<T>>{
public TTRCStepRenderFlagManagerDelegate(U viewManager) {
super(viewManager);
}
Override
public void setProperty(T view, String propName, Nullable Object value) {
switch (propName) {
case "traceId":
mViewManager.setTraceId(view, value == null ? null : (String) value);
break;
case "stepName":
mViewManager.setStepName(view, value == null ? null : (String) value);
break;
default:
super.setProperty(view, propName, value);
}
}
}
```
The problem is that `FbReactTTRCStepRenderFlagManager` doesn't extend `BaseViewManager`, but `ViewManager`, which means that we cannot use it with the generated delegate. We cannot use `ViewManager` instead of `BaseViewManager` in our JS codegen either, otherwise we will not be able to set base view props.
This diff makes it possible for delegates generated by JS to be used by Android view managers that do not extend `BaseViewManager`. By having a `BaseViewManagerInterface` we will be able to introduce a no-op base view manager implementation and wrap our original view manager in it so that we can pass as a constructor parameter to `BaseViewManagerDelegate`.
See an example of this approach for `FbReactTTRCStepRenderFlagManager`:
```
public class FbReactTTRCStepRenderFlagManager extends ViewManager<FbReactTTRCStepRenderFlag, ReactShadowNodeImpl> implements TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> {
private final ViewManagerDelegate<FbReactTTRCStepRenderFlag> mDelegate;
public FbReactTTRCStepRenderFlagManager() {
mDelegate = new TTRCStepRenderFlagManagerDelegate<>(new ViewManagerWrapper(this));
}
...
private static class ViewManagerWrapper extends BaseViewManagerAdapter<FbReactTTRCStepRenderFlag> implements TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> {
private final TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> mViewManager;
private FbReactTTRCStepRenderFlagManagerAdapter(TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> viewManager) {
mViewManager = viewManager;
}
Override
public void setTraceId(FbReactTTRCStepRenderFlag view, Nullable String traceId) {
mViewManager.setTraceId(view, traceId);
}
Override
public void setStepName(FbReactTTRCStepRenderFlag view, Nullable String stepName) {
mViewManager.setStepName(view, stepName);
}
}
}
```

Summary:
This one is fun.
# What?
Previously, the codegen'd constructor for a prop value in CPP was defined like so: `value(convertRawProp(rawProps, "value", sourceProps.value, value))`.
The fourth argument there is the default value of the result of `convertRawProps`. What that is saying is: the default value of `value` is `value` - the default value is itself.
The assumption was that because value is defined as `T value{someDefaultValue}` in the struct, in other words, because it has a default value in the `.h` file, that it will /start out/ being equal to `someDefaultValue`, and then be overridden later optionally, or be set to itself, which should be `someDefaultValue`.
However, that is not how initialization of class members in C++ constructors work. If a class member is in the member initializer list, [then the default value is not set](https://en.cppreference.com/w/cpp/language/initializer_list). That means that if the `defaultValue` as passed is /ever/ used, we incur undefined behavior.
# When is the defaultValue used?
The defaultValue is only used when no prop or a null value is sent from JS to C++: https://our.intern.facebook.com/intern/diffusion/FBS/browse/master/xplat/js/react-native-github/ReactCommon/fabric/core/propsConversions.h?commit=becfded106d706e6028e705d7883483051061e9f&lines=60
In most cases, the `sourceProps.value` is actually used as a fallback (the previous props value). The first time props are ever constructed, `sourceProps` should have valid values since it goes through a different path where only the defaultValues from props.h are used.
# Why wasn't this crashing before?
Most codegen'd properties are ints, floats, doubles, and bools. They might get wacky values, but they won't crash. I wouldn't be surprised if this diff solves some subtle visual or layout bugs, but I have no evidence of this yet.
# How do non-codegen'd props.cpp initialize default values?
Same as this diff does: defaultValue should be explicit everywhere: https://our.intern.facebook.com/intern/diffusion/FBS/browse/master/xplat/js/react-native-github/ReactCommon/fabric/components/scrollview/ScrollViewProps.cpp?commit=2813789c292dfdf1220b88f203af6b33ba9e42de&lines=51

How js script works:
