mkarchiso: add uefi-ia32.systemd-boot.esp and uefi-ia32.systemd-boot.eltorito boot modes
The systemd 254.2-1 package ships with IA32 systemd-boot, so it is possible to use for booting on IA32 UEFI. Perhaps they will be useful in the future. At least for now, the baseline and releng profiles are not changed to use them. When the issues and headaches caused with GRUB reach a critical point, then we will switch.

- Add bolt to releng for authorizing and otherwise managing Thunderbolt and USB4 devices.
|

- Add ``uefi-ia32.systemd-boot.esp`` and ``uefi-ia32.systemd-boot.eltorito`` boot modes that use systemd-boot for IA32
|

UEFI. The boot modes of baseline and releng are not changed.
