Do not store .cpp/.h files inside src/main/java - reactnativeblob (#3…

…4421)

Summary:
Pull Request resolved: #34421

Currently we expose native code (.h, .cpp) inside the src/main/java folder.
This is making impossible for users on New Architecture to open the project
inside Android Studio.

The problem is that the src/main/java is reserved to Java/Kotlin sources only.
AGP 7.2 also removed support for mixed source roots:
https://developer.android.com/studio/releases/gradle-plugin#duplicate-content-roots

This is essentially forcing users to write Java code without any autocompletion
as all the React Native Java classes are considered C++ files.

I'm addressing this issue folder by folder by moving them
from ReactAndroid/src/main/java/com/facebook/... to ReactAndroid/src/main/jni/react/...

This is the diff for reactnativeblob
