Kevin Gozali 3af21381df Codegen Android: allow generating Fabric Java component files during build time
Summary:
This commit:
* Generate Fabric component Java files along side Java NativeModule specs, when `USE_FABRIC=1` is set
* Adjust the component codegen to place output files in a subdir based on package name
* Adjust existing Buck targets to filter the right nativemodule vs component java files (this avoids duplicated symbols)
* Compiles the Java output during build time on RNTester/ReactAndroid (Gradle)

Not in this commit:
* Fabric C++ files
* Removing checked-in generated component files.

Kevin Gozali 13d9927a48 Codegen: separate Android/Cxx/iOS modules codegen outputs
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

Héctor Ramos d03c0f965e Generate FBReactNativeSpec ObjC++ source files using CocoaPods
Summary:
Move FBReactNativeSpec codegen invocation to shared `react_native_pods.rb` script and trigger codegen to run as part of `pod install` in both RNTester as well as React Native for iOS projects.

These files need to be generated before CocoaPods generates the Pods project, so the codegen is invoked as part of a `pre_install` hook during `pod install`.

The codegen hook can now take optional paths to allow it to run within different contexts (as part of a `react-native` repo checkout with access to the codegen source, or as part of a React Native iOS project that depends on the `react-native-codegen` npm package).

## Motivation

The FBReactNativeSpec ObjC++ source files (FBReactNativeSpec.h and FBReactNativeSpec-generated.mm) can be generated on demand from the native module specs in `Libraries/` using `react-native-codegen`. They can therefore be removed from the repository, but before we do so, we must ensure they get generated when a React Native iOS workspace is created or updated.

Invoking the codegen as part of the `pod install` step that creates a React Native iOS Xcode workspace ensures the specs are available in the following scenarios:
* Whenever a new React Native iOS project is created. The `react-native init` command invokes `pod install`.
* Whenever a React Native iOS project is upgraded. The `react-native upgrade` command invokes `pod install` as well.
* For contributors to the open source project running the RNTester application, the codegen will be invoked when the RNTester workspace is generated by CocoaPods using `pod install` in `packages/rn-tester`.

In any other case, the codegen can still be invoked directly via `scripts/generate-native-modules-specs.sh`.

> **Note:**
> The codegen will only process native modules in React Native's own Libraries directory.

[iOS][Changed] - Generate FBReactNativeSpec ObjC++ source files using CocoaPods.

Kevin Gozali 8cca54a7a7 Codegen Android: adjust JNI output to compile from Gradle
Summary:
This adjusted the C++ output for Android codegen (NativeModule specs) so we can compile it with ndk-build in Gradle:
* Use `#include` instead of `#import` for header files
* Added `#pragma once`
* Removed direct include of `<fb/fbjni.h>` -- this is not necessary
* Added generated Android.mk file based on library name

Kevin Gozali 22e3f020fd Codegen: create java dirs based on javaPackageName for .java spec files
Summary:
Move the directory creation logic to the CLI. This needs to be processed by RNCodegen.js eventually.

Kevin Gozali 0351c57e6a Codegen: Generate module C++ lookup function for JNI next to the spec classes
Summary:
The TurboModule system requires a lookup function to map the spec name (name used in JS) to the C++ TurboModule subclass. This is a pure C function. For now, generate one lookup function per set of modules found in the codegen schema.

Kevin Gozali 02fed06340 Codegen: Add JNI C++ generator for TurboModule subclasses
Summary:
This adds the C++ classes for Android, just like checked in here: https://github.com/facebook/react-native/tree/master/ReactAndroid/src/main/java/com/facebook/fbreact/specs/jni

The whitespace/formatting is slightly different but the functionality should be preserved.

Summary:
Use transpiled `react-native-codegen` scripts. By avoiding use of flow-node, we no longer need to upgrade flow-remove-types in order to run the native modules codegen script.

The interface for the script remains the same:
