x/mobile: enable to import multiple aar files compiled by gomobile for one Android Studio project

[MrKrisYu]

The goal of this issue

Intended to fix issuse #56567

What do I modify for gomobile

1. modify mobile/bind/java/Seq.java for extracting the java dependency(common Java dependencies later used for multiple AARs);
2. mkdir a directory named "libs" for storing common java dependencies;
3. modify mobile/cmd/gomobile/bind_androidapp.go to not cover go module in the class.jar of the final aar file.
4. add some descriptions for how to using the new feature.

Details

more details, please see my fork : https://github.com/MrKrisYu/mobile

Does iOS have the same issue?

iOS gives the following warnings but it works:

objc[16342]: Class GoSeqRef is implemented in both /private/var/containers/Bundle/Application/77FA4478-30D1-4F07-BBA9-24F0DCDBD12F/Example.app/Frameworks/GoLib.framework/GoLib (0x10708fc08) and /private/var/containers/Bundle/Application/77FA4478-30D1-4F07-BBA9-24F0DCDBD12F/Example.app/Example (0x10551fa40).
One of the two will be used. Which one is undefined.

A similar warning is printed for following classes: Universeerror, goSeqDictionary, GoSeqRef, RefCounter, RefTracker.

Hey! thank you for this changes but when I completely do all steps which you are mention in your repository and run the below command it show me the error:

My last command: gomobile bind -target=android wrapTun -v

After when I tried to compile https://github.com/2dust/AndroidLibXrayLite with https://github.com/MrKrisYu/mobile
I got an error message:
error: package go does not exist import go.Seq;

iOS 给出了以下警告但它可以正常工作：

objc[16342]: Class GoSeqRef is implemented in both /private/var/containers/Bundle/Application/77FA4478-30D1-4F07-BBA9-24F0DCDBD12F/Example.app/Frameworks/GoLib.framework/GoLib (0x10708fc08) and /private/var/containers/Bundle/Application/77FA4478-30D1-4F07-BBA9-24F0DCDBD12F/Example.app/Example (0x10551fa40).
One of the two will be used. Which one is undefined.

以下类会打印类似的警告：Universeerror、goSeqDictionary、GoSeqRef、RefCounter、RefTracker。

Have you solved the problem that Class GoSeqRef is implemented in both

Please see the changes in my branch. I managed to fix this issue. The app runs like a normal one, but there are still some problems. I came to the conclusion that Go Mobile has no way to manage multiple AARs.

禁止熬夜

https://github.com/khayyamov/mobile/tree/wireguardwarp 请查看我的分支中的更改。我设法修复了这个问题。应用程序运行起来像普通应用程序一样，但仍然存在一些问题。我得出的结论是 Go Mobile 无法管理多个 AAR。

I compiled the xcframework, but the Class RefTracker is implemented in both also appeared in the iOS project

iOS 有同样的问题吗？

iOS also has the problem of multiple implementations of the same class：goSeqDictionary、GoSeqRef、RefCounter、RefTracker
