components store unions as 'StringEnumTypeAnnotation' even though it isn't actually a union, it's a literal.
Native Modules store these as 'StringLiteralTypeAnnotation' so this converges those and reuses the same types.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/44294
**Problem:**
It was discovered while testing 3 party library, generated member variables in a C++ `struct` in `Props.h` is not initialized.
Also `WithDefault` would not work as well.
(For the problematic case it was a `boolean` but would also apply to other primitive types.)
If there is no default initialization and the component prop is optional and the user of the native component does not set the prop then the variable is never initialized and this is problematic for primitive types in C++ where no initialization results in an undefined behavior.
**Proposed solution:**
(Following C++Core Guideline of [always initialize](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Res-always).)
Reusing `generatePropsString()` used by `ClassTemplate` to generate props for `StructTemplate` as well.
updated relevant test snapshots.
This change is only concerning the `Props.h` file.
**Changelog:**

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/42956
In the component codegen system, when the header prefix is an empty string, we generate includes using angle brackets, like this:
```
#include <EventEmitter.h>
```
This fails to compile in buck.
If we instead generate includes using quotations, buck compiles again.
```
#include "EventEmitter.h"
```
So, changes: if the headerPrefix is an empty string, generate includes using quotes.
This is a followup to D51811596.

It supports the generation of Array of:
- Boolean
- Int32
- Float
- Double
- String
- Objects
- Array
**Note:** This is a first iteration. We could improve the generation further by leveraging the `Bridging` module within React Native.

Generate enum types in c++ turbo modules.
For enums in the ts schema file such as:
```
export enum NumEnum {
ONE = 1,
TWO = 2,
}
```
This would export enums and the relevant Bridging to js and from js code to the spec H files such as:
```
#pragma mark - SampleTurboModuleCxxNumEnum
enum SampleTurboModuleCxxNumEnum { ONE, TWO };
template <>
struct Bridging<SampleTurboModuleCxxNumEnum> {
static SampleTurboModuleCxxNumEnum fromJs(jsi::Runtime &rt, int32_t value) {
if (value == 1) {
return SampleTurboModuleCxxNumEnum::ONE;
} else if (value == 2) {
return SampleTurboModuleCxxNumEnum::TWO;
} else {
throw jsi::JSError(rt, "No appropriate enum member found for value");
}
}
static jsi::Value toJs(jsi::Runtime &rt, SampleTurboModuleCxxNumEnum value) {
if (value == SampleTurboModuleCxxNumEnum::ONE) {
return bridging::toJs(rt, 1);
} else if (value == SampleTurboModuleCxxNumEnum::TWO) {
return bridging::toJs(rt, 2);
} else {
throw jsi::JSError(rt, "No appropriate enum member found for enum value");
}
}
};
```
That code would allow us to use these enums in the cxx files like this:
```
NativeCxxModuleExampleCxxEnumInt getNumEnum(
jsi::Runtime &rt,
NativeCxxModuleExampleCxxEnumInt arg);
```

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:
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
