Orbot Using Tor Android Service

I'd like to get some discussion of whether we want to have Orbot start using Tor Android Service/TOPL. It's stable now so worth a look.

I have a pull request with some refactoring that would help with eventual integration if we go that route. https://github.com/guardianproject/orbot/pull/240

I'm tracking issues with #31042 (moved) to align the code with the latest changes so we don't get out of sync.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
