Pull Request resolved: https://github.com/facebook/react-native/pull/32840Closes#31516
I've cherry-picked the original PR that had merge conficts + updated all
the headers as the one for the TurboModule generators were not handled.
Original Commit Message from acoates
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
saying the file was codegen'd and so the file shouldn't be manually edited.
Open to suggestions on what the comment header should say.
Changelog:
[General] [Changed] - Do not include Facebook license on users codegen'd code

Summary:
## Rationale
**Disclaimer**: This is an incremental step towards more maintainable/readable react-native-codegen generators. In the future, we may want to replace these templates/string concat logic with *something better*. But until we decide what that *something better* is, let's at least get rid of all this gross string find/replace.
Benefits of using Function templates over String.prototype.replace.
- **Self-documenting**: Template Functions enumerate/describe their exact data dependencies in their signature. You no longer have to read the template implementation to see what data you need to pass into the template.
- **Improved Readability**: JavaScript syntax highlighting makes it really easy to see where/how the data is inserted into the templates. Also template variables used be prefixed/suffixed with ::, which made things really confusing in C++ code (e.g: wtf is `::_CLASSNAME_::EventEmitter::::_EVENT_NAME_::`?).
- **Simpler Interpolation**: Don't have to worry about .replaceAll vs .replace, or calling these replace functions with regexes or strings.
- **Template Type-safety**: Ensure that the correct data types are passed to the component templates (e.g: flow will complain if you accidentally pass null/undefined when a template expects a string).
- **Template Type-safety**: Ensure that we don't pass in extra data to templates (this diff catches/fixes instances of this error). Ensure that we don't forget to pass in data to the template.
- etc.
After this diff, both our Component and NativeModule generators will be using template functions. This string find/replace exists no more in react-native-codegen.
This is also a very surface-level change. I made no efforts to simplify these templates. Let's take a look at that later, as necessary.

Changelog:
[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:
For now, separate the definition of `modules` generator per platform to avoid file output collision. Additionally:
* For Android, produce files under java/ (plus nested subdirs based on packageName) and jni/ (for C++ files) - JavaPoet version already does it
* Allow configuring packageName for Android - JavaPoet version has this
* Avoid tmp directory dance in the CLI script, given the proper modules separation

NOTE: Flow and Jest won't pass on this diff. Sandcastle, should, however, be green on D24236405 (i.e: the tip of this stack).
## Changes
Previously, the "Module" schema could either contain a `components` property, or a `nativeModules` property. The existence of the `components` property was used to determine (1) if the generators would run and (2) filter schemas on which the generators would run. Now, we simply check whether the type of the "Module" schema is `Component`.

Summary:
Following our internal discussion we want to change previously used name convention.
Now it looks like:
```
#import <FBReactNativeTestSpec/FBReactNativeTestSpec.h>
```
Name is a param of `rn_codegen` and `rn_library`. Also, I found it the easiest to move replacing `::_IMPORT_::` into buck rule
