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);
```

Codegen for props parsing was failing to add a required include for the case when the type is an array of objects, which in turn use non-trivial types.
Something like:
```
export type NativeProps = $ReadOnly<{
...ViewProps,
bounds: $ReadOnlyArray<
$ReadOnly<{
height?: Float,
left?: Float,
top?: Float,
width?: Float,
}>,

This fixes#35864
This feature allows using `$Partial<Obj>` in flow and `Partial<Obj>` in TypeScript based on the spec mentioned here: https://flow.org/en/docs/types/utilities/#toc-partial.
We currently only allow passing an Obj to Partial so
```
export type SomeObj = {
a: string,
b?: boolean,
};
export type PartialSomeObj = Partial<SomeObj>;
```
should work.
and also-
```
export type PartialSomeObj = Partial<{
a: string,
b?: boolean,
}>;
```
But not
```
export type PartialSomeObj = Partial<Partial<{
a: string,
b?: boolean,

```
This can be improved in the future by a recursive unwrapping of the value inside the `Partial` annotation.

The feature has been largely requested by the OSS community but it could be also helpful for people in Meta.
To allow the generation of custom `NativeState`, we first have to always generate a `ViewEventEmitter`: that's because the `ConcreteShadowNode` template lists the Generics with this order: `Name`, `Props`, `EventEmitter`, Others...
If we skip the `EventEmitters` and we put the `State`, React Native would think that the State is actually an `EventEmitter` and the build step will fail.

* Add an `Android-prebuilt.cmake` file that works similar to the `Android-prebuilt.mk` for feeding prebuilt .so files to the consumer build.
* Update the codegen to use `JSI_EXPORT` on several objects/classes as CMake has stricter visibility rules than Make

The codegen generates a Facebook copyright notice at the top of the generated files.
While this might make sense on the core files, this codegen will be run on external components too.
The notice also refers to a LICENSE file in the root of this project, which might not be there if this is run on another project.
I did a quick look at some of the codegen that we ship within windows dev tools, and it looks like we normally just have comments

Summary:
## Context
Inside native ViewConfigs, events are declared using these bubbling/direct EventType maps:
```
{
uiViewClassName: '...',
bubblingEventTypes: {
topFoo: {
registrationName: "onFoo"
}
},
directEventTypes: {},
validAttributes: {
},
}
```
**Pattern:** Note that the top name (i.e: topFoo) is just the registration name (i.e: onFoo) but with "on" replaced with "top".
On Android, registration names and top names don't have to follow this pattern. The top name can be **anything.** See ReactionsDockView:
https://www.internalfb.com/code/fbsource/[c430d46ed69a03a9d9f40cefa335a6d8bb92f8ec]/fbandroid/java/com/facebook/feedback/reactions/ui/overlay/react/ReactionsDockViewManager.java?lines=26-28%2C32-34%2C38
Here, ReactionDismissedEvent.EVENT_NAME is "topDismiss"
https://www.internalfb.com/code/fbsource/[c9f92314a5c46e561a831100dab82164808b05d0]/fbandroid/java/com/facebook/feedback/reactions/ui/overlay/react/ReactionDismissedEvent.java?lines=10-11%2C26
And so to provide you the flexibility to specify a custom topName, the codegen supports a customTopName in the direct/bubbling event types:
```
onDismissWithFeedbackReaction: DirectEventHandler<Event, 'topDismiss'>,
```
This generates the two bubbling event type entries in ReactionsDockView:
```
{
uiViewClassName: '...',
bubblingEventTypes: {
// custom top name
topDismiss: {
registrationName: "onDismissWithFeedbackReaction"
},
// what the top name should actually be
topDismissWithFeedbackReaction: {
registrationName: "onDismissWithFeedbackReaction"
}
},
directEventTypes: {},
validAttributes: {
},
}
```
**The Problem:** The entry created for "topDismissWithFeedbackReaction" is not necessary. This additional entry creates a discrepancy between ReactionsDockView's static ViewConfig and native ViewConfig. Therefore, this diff removes the second unnecessary entry.

Looks like we use the name of the prop as a variable name during codegen, and this can conflict with some other hardcoded variable names.

[iOS][Added] - Description
When compiling iOS apps with flag `-Wnullability-completeness` (like Lightspeed app and soon Instagram), Objective-C headers are required to either have full *explicit* nullability annotations on all members of its public API, or none at all; partially annotated headers will fail to build that module.
RN native modules are currently generated with *partial* annotations. This works today because most apps are not compiled with `-Wnullability-completeness` turned on. But when we flip the switch for Instagram, the app doesn't build due to importing these RN partially annotated modules.
JavsScript Flow types are implied nonnull, and the current RN codegen translates Flow's [maybe/optional](https://flow.org/en/docs/types/maybe/) type to Obj-C `_Nullable` annotation, and everything else without an explicit Obj-C annotation. However this creates a mismatch with the Obj-C type system, where the implied default is *unannotated*, which is handled differently from nonnull when built with the nullability compiler flags.
There is a simple Obj-C macro that automatically adds *explicit nonnull* annotations to all members in a header: `NS_ASSUME_NONNULL_BEGIN` / `NS_ASSUME_NONNULL_END`. If we add this to *all* RN-generated headers, however, we run into issues:
1) We may erroneously assume any previously-unannotated header was meant to be nonnull and cause future bugs
2) Another compiler flag (`-Wnullable-to-nonnull-conversion`) statically analyzes Obj-C implementation code to prevent us from ever passing null to one of these headers. Much existing Obj-C code will break here, and it's ambiguous if these are true or false positives because of the first point.
Instead, in this diff we add a new BUCK flag `ios_assume_nonnull` to let module authors opt into automatic nonnull for unannotated members so that Obj-C headers are generated correctly in alignment with Flow's type system. We can migrate all libraries individually as needed and eventually make this the RN native codegen default.

Summary:
## Problem
Suppose we have this NativeModule spec, that uses Object literals that contain a property called "id":
```
export interface Spec extends TurboModule {
// Exported methods.
+getConstants: () => {|
id: string,
|};
+getObject: (arg: {id: Object}) => Object;
}
```
For both object literals, we'll generate C++ structs, backed by NSDictionaries. The method in each struct will be named "id_" to avoid a name clash with ObjC's `id` identifier. However, calling that id_ method should still access the "id" property in the corresponding NSDictionary.
## Expected Output
```
inline id<NSObject> JS::NativeSampleTurboModule::SpecGetObjectArg::id_() const
{
id const p = _v[@"id"];
return p;
}
inline JS::NativeSampleTurboModule::Constants::Builder::Builder(const Input i) : _factory(^{
NSMutableDictionary *d = [NSMutableDictionary new];
auto id_ = i.id_.get();
d[@"id"] = id_;
return d;
}) {}
```
## Actual Output
```
inline id<NSObject> JS::NativeSampleTurboModule::SpecGetObjectArg::id_() const
{
id const p = _v[@"id_"]; // <-- HERE!
return p;
}
inline JS::NativeSampleTurboModule::Constants::Builder::Builder(const Input i) : _factory(^{
NSMutableDictionary *d = [NSMutableDictionary new];
auto id_ = i.id_.get();
d[@"id_"] = id_; // <-- HERE!
return d;
}) {}

2. Tangential: We're no longer removing the `Native` prefix from the NativeModule filename, assuming that that's the module name (problem: wrong), and prefixing again with Native (problem: redundant), when we're generating code. Instead, like the internal codegen, we simply pass the filename to the Codegen output. Our linters enforce that all NativeModule specs are contained with files that start off with `Native`.

Summary:
This diff:
1. Simplifies the NativeModule schema Flow types.
2. Simplifies the NativeModule Flow parser, to accomodate the modified schema, and to reduce code duplication.
**Notes:**
- If the parser detects an unrecognized type within the context of parsing an Array's element type, it'll omit the `elementType` property of the `ArrayTypeAnnotation`. Details: T72031674. **Rationale:** Basically, when an array element type is supported, we use it in our generators. When it's unsupported, we ignore it. In the unsupported case, there's no point in trying to parse the Array element type, which is why I decided to omit the `elementType` property. Ideally, our NativeModule specs would never use unsupported types, in any context. This would allow us to always parse and use the elementType. However, that seems like a it could be a hefty migration: we have > 400 specs. Since, this isn't a battle we need to fight right now, I left a TODO at the relevant lines instead.
- The legacy codegen would generate structs for each object literal type in the file. In this re-implementation of the parser, I only insert into the aliases array when we detect a usage of a type-alias to an ObjectLiteral type annotation. With this decision, we won't be able to generate these unnecessary structs. This is good because we get rid of dead code. It's bad because it might make our migration to this codegen bit more difficult.
