There are two places where we use a feature specific to the system version of 'cp', the:
-X Do not copy Extended Attributes (EAs) or resource forks.
This feature isn't available in GNU's cp, which is commonly installed on macOS using:
brew install coreutils && brew link coreutils
We can avoid the problem alltogether by being specific about the path of the system cp.
Changelog: [General][Fixed] don't break script phase and codegen when coreutils installed on macOS

**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:**
[General][Fixed] - fixed `Props.h` created from codegen missing default initializers in C++ `struct`

Summary:
After discussing with mdvacca, we prefer to undo the change of `TurboModule` package to `.internal` as this is a quite aggressive breaking change for the ecosystem.
Moreover: users should not invoke `TurboModule.class.isAssignableFrom` because `TurboModule` is `.internal`. Therefore I'm exposing another API to check if a class is a TurboModule as a static field of `ReactModuleInfo`.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/42812
There is a way of defining events where you specify additional string type parameter in the EventHandler in the spec. This additional type parameter is an overridden top level event name, that can be completely unrelated to the event handler name.
More context here D16042065.
Let's say we have
```
onLegacyStyleEvent?: ?BubblingEventHandler<LegacyStyleEvent, 'alternativeLegacyName'>
```
This will produce the following entry in the view config:
```
topAlternativeLegacyName: {
phasedRegistrationNames: {
captured: 'onLegacyStyleEventCapture',
bubbled: 'onLegacyStyleEvent'
}
}
```
This means that React expects `topAlternativeLegacyName`.
But the generated EventEmitter looks like this:
```
void RNTMyNativeViewEventEmitter::onLegacyStyleEvent(OnLegacyStyleEvent $event) const {
dispatchEvent("legacyStyleEvent", [$event=std::move($event)](jsi::Runtime &runtime) {
auto $payload = jsi::Object(runtime);
$payload.setProperty(runtime, "string", $event.string);
return $payload;
});
}
```
The native component will emit `legacyStyleEvent` (`topLegacyStyleEvent` after normalization) that React will not be able to handle.
This issue only happens on iOS because Android doesn't use EventEmitter currently.
To address this issue we'll use `paperTopLevelNameDeprecated` for the generated EventEmitters if it is defined.
Changelog: [iOS][Fixed] - Fixed support for event name override in component specs.

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.

Summary:
### The problem
1. We have a library that's supported on iOS but doesn't have support for visionOS.
2. We run pod install
3. Codegen runs and generates Code for this library and tries to reference library class in `RCTThirdPartyFabricComponentsProvider`
4. Example:
```objc
Class<RCTComponentViewProtocol> RNCSafeAreaProviderCls(void) __attribute__((used)); // 0
```
This is an issue because the library files are not linked for visionOS platform (because code is linked only for iOS due to pod supporting only iOS).
### Solution
Make codegen take Apple OOT platforms into account by adding compiler macros if the given platform doesn't explicitly support this platform in the native package's podspec file.
Example generated output for library supporting only `ios` and `visionos` in podspec:
I used compiler conditionals because not every platform works the same, and if in the future let's say react-native-visionos were merged upstream compiler conditionals would still work.
Also tvOS uses Xcode targets to differentiate which platform it builds so conditionally adding things to the generated file wouldn't work.

At the end of last year, we reduce build fragmentation in iOS making sure that we were always building both architecture.
In the process, we break the semantic od RCt_NEW_ARCH_ENABLED flag, making several libs stop working in one of the two archs.
This change should restore the semantic, so libraries that were using RCT_NEW_ARCH_ENABLED to run conditional code will still work in the same way. While doing so, I also removed the new USE_NEW_ARCH as we don't want unnecessary flags
## CHANGELOG:

Pull Request resolved: https://github.com/facebook/react-native/pull/41956
By default, generated Cxx sources for components all end up in same directory. However the include declarations in them look like this:
```
#include <react/renderer/components/${libraryName}/ShadowNodes.h>
```
And not like this:
```
#include "ShadowNodes.h"
```
This works fine with Buck because it supports header prefixes.
To get this working with CocoaPods we define additional `HEADER_SEARCH_PATHS` for our `React-Codegen` pod.
This approach will not work if we want to generate code at the library level and check in the artifacts. That's because we don't have control over the Podspec there, and can't inject those additional `HEADER_SEARCH_PATHS`.
This diff adds the `headerPrefix` argument to the codegen entry point. It is `react/renderer/components/${libraryName}` by default, but can become empty if we want to generate code at the library level, and don't want to deal with this nested header structure.
*Note:* `RNCodegen` runs all the generators [in a loop](https://github.com/facebook/react-native/blob/main/packages/react-native-codegen/src/generators/RNCodegen.js#L263-L275), assuming that the all have same function signature So I had to add the `headerPrefix` argument to all the generators, even to the ones that don't really need it.
