feat: add initial implementation for JDWP debugger

[itsaky-adfa]

Injection

• Write a Gradle Plugin which hooks into the APK build and adds our own
  oj-libjdwp shared libraries to the jniLibs of the project.

• If the application does not specify an implementation of android.app.Application in its AndroidManifest.xml file, inject our own implementation of android.app.Application class into the project.

• If the application already has an implementation of android.app.Application, make our implementation extend the Application class of the target application.

• Update the manifest to specify our own implementation of android.app.Application.

• Update the manifest to ensure that android.permission.INTERNET is requested by the target application. This is required for the socket communication.

Working

Our implementation of android.app.Application class :

• Checks if the target application is running on API >= 28.
• If not, don't bother to start the debugger agent.
• Otherwise, start the agent with the options provided by CoGo.

After the agent has been attached, a normal JDWP connection can be initiated between CoGo and the target application.

Requires

• PR: ADFA-367: remove need for LayoutEditor symlink #105
