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);
```

> **Notice**: This commit does not change any behaviour.
Parse and collect enum members in module specs instead of the current behaviour of parsing enum members as 'string' / 'number' and ignoring the member names.
This commit would allow us to generate native Enums corresponding to the schema's enums.
Prior to this commit, enum params were parsed as:
```
{
'name': 'qualityParam',
'optional': false,
'typeAnnotation': {
'type': 'EnumDeclaration',
'memberType': 'StringTypeAnnotation'
}
},
```
The name of the enum type and the members of the enum type were ignored.
After this commit, parsed modules would hold a new object member called `enumMap` that would look like this:
```
'enumMap': {
'QualityEnum': {
'name': 'QualityEnum',
'type': 'EnumDeclarationWithMembers',
'memberType': 'StringTypeAnnotation',
'members': [
{
'name': 'SD',
'value': 'sd'
},
{
'name': 'HD',
'value': 'hd'
}
]
},
// ...
}
```
And enum params would be exported as:
```
{
'name': 'qualityParam',
'optional': false,
'typeAnnotation': {
'name': 'NativeModuleEnumTypeAnnotation',
'type': 'EnumDeclaration',
'memberType': 'StringTypeAnnotation'
}
},
```
Combining the two new outputs would allow us to generate Native enums in the Native generators.

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,
}>,

Summary:
While working on D42008409 I found out that codegen for pure C++ modules doesn't work with container types that are nested inside generated data structures, which happens because they don't have a specialization of `bridging::toJS` that wouldn't pass the `invoker` instance through.
It looks like an easiest option would be just to use `invoker` in codegen for `toJS` as well, which this diff does.
Note that I also experimented with removing `invoker` from being used in the `::toJS` specializations for containers altogether (see D42008410), as there doesn't seem to be a single use case when `invoker` would be ever needed in any `::toJS` specialization (and imagining such a scenario would be a stretch, tbh - why a conversion function would invoke anything running on JS side, given that invoker provides no return values anyway?..)
But since I am still not 100% about the invoker purpose there, I went with the codegen change.

Summary:
We have the expected module name available as part of the codegen schema, so we can remove the need for developers to implement the `getName` method as part of their module implementation.
Note that this method is not actually used when the TurboModules infra is used, as the moduleName from the turbo module manager is passed through to the TurboModule base class instead. Moving the method to codegen will make it easier to remove this method altogether once the old architecture is fully removed.

flow --json --pretty | jq '.errors | .[] | .message | .[] | .loc |.source' | sort | uniq | sed -e 's/"//g' | xargs hg revert

Summary:
This is the second diffs that backs out the Custom Native State from the Codegen. The reason why we are backing it out are:
1. It forces users to create new types in JS that are not ctually used there. For example, the NativeState you define, and eventually exports, in JS is not used anywhere in your JS code.
2. You need to put in the JS native state some types that does not exists in JS, only to have them generated by the Codegen. ImageRequest, for example, does not exists in JS, but you need it in your (iOS) state to load images
3. There are a lot of edge cases due to how C++ handles variables. Some variables needs to be created as pointers. Some others as `const &`. It does not scale to hard code all of them and there is the risk to have the same type that needs to be a pointer in some case and something else in others.
4. It is better to instruct the users on how to properly create a component with Custom State, Shadow Node and Descriptor.

This Diff is the first step of enabling the CodeGen to parse and generate a NativeState for the components.
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.

Summary:
When `GenerateRCTThirdPartyFabricComponentsProviderCpp.js` generates `RCTThirdPartyFabricComponentsProvider.mm` an edge case happens in the following situation:
- The same library exports multiple modules with one component each (i.e. one component per file);
- The **first component** is excluded for iOS via the `excludedPlatforms` property in *codegenNativeComponent*.
A "loose" comma appears in the generated template, breaking the code.
```c++
Class<RCTComponentViewProtocol> RCTThirdPartyFabricComponentsProvider(const char *name) {
static std::unordered_map<std::string, Class (*)(void)> sFabricComponentsClassMap = {
, // <-- the offending comma
{"NativeComponent2", NativeComponent2Cls}, // rnmylibrary
};
}
```
At some point, `GenerateRCTThirdPartyFabricComponentsProviderCpp.js` does not properly filter out empty arrays resulting from excluded components. This does not seem to be a problem when the excluded component is not the first being processed, as the comma gets added at the end of the previous line, after the comment with the name of the library.

This is the schema that leads to the bug. Notice that the first component was excluded for iOS.
```json
{
"modules": {
"ComponentFile1": {
"type": "Component",
"components": {
"NativeComponent1": {
"excludedPlatforms": ["iOS"]
"extendsProps": [
{

}
],
"events": [],
"props": [],
"commands": []
}
}
}
}
```
`GenerateRCTThirdPartyFabricComponentsProviderCpp.js` should generate a template without the comma in the wrong position (before NativeComponent2).
I also added an additional test case to cover this problem. All the other tests passed.

Summary:
There are cases where we want to pass an enum type into a TurboModule method which is handy to restrict certain arguments to a restricted set of values, e.g. restricting quality to ```enum Quality { SD, HD, }```
Approach:
- We are not generating an ```enum``` type in C++ but rather just cast type safe to the corresponding member type.
- We don't support mixed enum types at this time, e.g. ```export enum StringOption { One = 'one', Two = 2, Three = 'three', };``` will not work. See: https://www.typescriptlang.org/docs/handbook/enums.html#heterogeneous-enums
- We only support untyped (default to String), String, and Number enum properties

In order to make this possible I had to:
* 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
* Update the sample native module in `nativemodule/samples/platform/android/` to use CMake instead of Make

Summary:
This fixes an issue where nullability was lost on readonly types in TurboModules specs. The "outside" nullability would be ignored in favor of only respecting the "inside" nullability (i.e. `?$ReadOnly<{}>` vs `$ReadOnly<?{}>`). It now ensure either is propagated correctly.
