Add architecture-specific boot configurators that translate the debian-cd boot shell scripts (boot-amd64, boot-arm64, boot-ppc64el, boot-riscv64, boot-s390x) into Python. The package uses a class hierarchy: - BaseBootConfigurator: abstract base with common functionality - GrubBootConfigurator: shared GRUB config generation - UEFIBootConfigurator: UEFI-specific shim/ESP handling - Architecture classes: AMD64, ARM64, PPC64EL, RISCV64, S390X A factory function make_boot_configurator_for_arch() creates the appropriate configurator for each architecture.
