Add support for nested exceptions

[yuki24]

This PR depends on rails/rails#32410.

This PR adds support for nested exceptions that is being discussed in the upstream Rails. The idea is to add an object scope using the exception_object_id and pass it to the web console session along with the frame_id, so the session will be able to switch the binding to the specified frame in the appropriate exception.

Obviously, there needs to be some test overage around this as this is touching the core functionality of the gem. But please let me know if there is any feedback.

Thanks @yuki24, left a few comments, but overall, it looks good!

@yuki24 I'm planning to merge this as is and do a few changes afterward myself. You can get back to it in a bit.

[yuki24]

I'm okay with that if you don't mind the test failures in CI. Let me know if there's anything I could help out!

[yuki24]

Alright, I've addressed the comments and added more test coverage. Let's touch base after the lightning talk.
