bsdinstall: Improve installer UI for mirrorselect and zfsboot

Refactored mirrorselect to organize mirrors by region using submenus, making it easier for users to locate appropriate mirrors based on geography.

Refactored zfsboot to use submenus for ZFS configuration options. This improves clarity and streamlines the installation process for users choosing ZFS setups.

Please don't spam our repository with AI-generated slop. It serves only to waste our time and yours. After reviewing some of your PRs, I have concluded that the rest do not warrant even a cursory review. Therefore I will close them all. If you wish to contribute again in the future, you must take more care with your submissions. You must build and test them all, at least! And you need to consider what the PR does. Is it even useful? Furthermore, the copyright status of AI-generated code is currently unclear, so the project is not accepting any such submissions at this time. But AI can of course be used as an aid, such as for debugging. Finally, I encourage you to read these documents to familiarize yourself with our project and its practices.
