Record GPU/TPU host changes in the change journal

Seven gpu_tpu scripts now write through the journal for host changes only — driver and package installs, vfio binding, modprobe.d, /etc/modules, GRUB and udev — while VM and LXC configuration stays out; add_gpu_vm and install_coral_lxc journal only their host writes. amd_gpu_tools records its install, and pmx_journal.sh gains pmx_record_uninstall while changes_journal.py retires an installed package when ProxMenux removes it. What each function writes is byte-identical to before, verified by tests/journal/verify_journal_migration.py.
