This is needed to be able to recurse into the literals and compare them.
I'm primarily unsure if there is a problem representing doubles/floats as numbers instead of strings though.

I need to reference this type somewhere else, but not an array of the type.
Generally we prefer that all exported types are the object itself, and it used as a member type of arrays when used.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/47323
This change adds support for number literals as a type.
The codegen already has parsing support for these types
```
+passNumber: (arg: number) => void;
+passString: (arg: string) => void;
+passStringLiteral: (arg: 'A String Literal') => void;
```
This change now also supports
```
+passNumberLiteral: (arg: 4) => void;
```
On the native side this is treated the same as `number`. It could be strengthened in the future.
This is a pre-requisite for number literal unions and enums.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/46845
Previously, the parser was throwing away the values of a string union when storing it in the schema. It would only store the union as
```
{
type: 'UnionTypeAnnotation',
memberType: 'StringTypeAnnotation'
}
```
We now track the string literals through the parser and store them in the schema:
```
{
type: 'StringLiteralUnionTypeAnnotation',
types: [
{
type: 'StringLiteralTypeAnnotation'
value: 'light'
},
{
type: 'StringLiteralTypeAnnotation'
value: 'dark'
},
],
}
```
We aren't changing the generators, those still just output "string". They could eventually be made smarter.
The value of this is that the compat checker can now error when the union changes.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/46827
You can now define a native module that takes an argument that is a specific string literal:
Like this:
```
export interface Spec extends TurboModule {
+passString: (arg: string) => void;
+passStringLiteral: (arg: 'A String Literal') => void;
}
```
On the native side, this will still generate `string`, but the schema will now store the string literal, and it will be allowed in JS. This should allow more strict flow / typescript types for modules.
This will also allow the compatibility check to fail if the literal changes.
This is a step towards accepting a union of string literals.

It makes scripts operating on the schema complicated when the elementType might be there or might not. Let's make it required, but VoidTypeAnnotation if it's unknown.
Arguably we shouldn't allow it to be unknown at all, but that's out of scope here.

Previously the schema special cased unparseable elementType with elementType just being undefined. This causes issues for logic that requires recursively matching types. Instead of being implicit, this makes them explicitly an AnyTypeAnnotation

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/44809
Adding react-native-codegen parser support for a new `EventEmitter` property type on C++ Turbo Modules.
It is possible to later expand this feature to other languages (Java, ObjC).
## Characteristics
An `EventEmitter` must:
- be non null:
`EventEmitter<string>` works, `?EventEmitter<string>` does NOT
- have a non null eventType:
`EventEmitter<number>` works, `EventEmitter<?number>` does NOT
- have at most 1 eventType, `void` is possible as well:
`EventEmitter<>` or `EventEmitter<MyObject>` work - `EventEmitter<number, string>` do NOT
- have a concrete eventType, `{}` is not allowed
`EventEmitter<{}>` does NOT work
- be used in `Cxx` Turbo Modules only at this time
## Example
For these 4 eventEmitters in on an RN JS TM spec
```
+onPress: EventEmitter<void>;
+onClick: EventEmitter<string>;
+onChange: EventEmitter<ObjectStruct>;
+onSubmit: EventEmitter<ObjectStruct[]>;
```
We now generate this code:
1.) in the spec based header `{MyModuleName}CxxSpec` in the constructor:
```
... // existing code
eventEmitterMap_["onPress"] = std::make_shared<AsyncEventEmitter<>>();
eventEmitterMap_["onClick"] = std::make_shared<AsyncEventEmitter<OnClickType>>();
eventEmitterMap_["onChange"] = std::make_shared<AsyncEventEmitter<OnChangeType>>();
eventEmitterMap_["onSubmit"] = std::make_shared<AsyncEventEmitter<OnSubmitType>>();
```
2.) as `protected` functions
```
void emitOnPress() {
std::static_pointer_cast<AsyncEventEmitter<>>(delegate_.eventEmitterMap_["onPress"])->emit();
}
void emitOnClick(const OnClickType& value) {
std::static_pointer_cast<AsyncEventEmitter<OnClickType>>(delegate_.eventEmitterMap_["onClick"])->emit(value);
}
void emitOnChange(const OnChangeType& value) {
std::static_pointer_cast<AsyncEventEmitter<OnChangeType>>(delegate_.eventEmitterMap_["onChange"])->emit(value);
}
void emitOnSubmit(const OnSubmitType& value) {
std::static_pointer_cast<AsyncEventEmitter<OnSubmitType>>(delegate_.eventEmitterMap_["onSubmit"])->emit(value);
}
```

Summary:
Previously we allow `{[key:string]:Something}` in codegen, `Something` is type-checked but thrown away, generating a `GenericObjectTypeAnnotation`.
In this change, `Something` is added to `GenericObjectTypeAnnotation` as an optional field.
For downstream code such as C++ codegen, this change is **backward compatible**. It allows C++ codegen to produce a more precious type optionally.

Summary:
- Add a typescript project to test `CodegenSchema.d.ts`. More tests for other .d.ts files will be added in future pull requests.
- The build script scans all snapshots from `react-native/codegen`'s typescript frontend and generates .ts files for each snapshot, but they are .gitignore-ed.
- `npm run build` will build these .ts files against `CodegenSchema.d.ts` after generating them.
- A failed jest case is included to ensure CI catch it, it will be removed before merged.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/36345
`exactOptionalPropertyTypes` is a TypeScript 4.4+ option set by users which changes behavior of optional properties, to disable accepting explicit `undefined`.
This is not enabled when using `--strict`, and is stricter than Flow, leading to most of the typings having an `| undefined` unique to TypeScript (added with https://github.com/DefinitelyTyped/DefinitelyTyped/commit/694c663a9486dbe7794d5eb894a691ee9ded318a).
We have not always followed this (I have myself previously assumed the two are equivalent). We can enforce that the convention is followed with a plugin `eslint-plugin-redundant-undefined`. This forces us to declare that every optional property accepts an explicit undefined (which Flow would allow). Alternatively, if we do not want to support this, we can enable the existing dtslint rule `no-redundant-undefined`.
