Use consistent formatting across all architectures: 4-space indent,
two spaces after "linux", one space after "initrd". Also fix an extra
blank line before "fi" in amd64's UEFI section caused by f-string
interpolation.

Separate config generation from file I/O by having generate_grub_config()
and its helpers return strings. The base class make_bootable() now handles
writing grub.cfg.

The debian-cd scripts did this game of placing boot-related files in a
separate directory that was then passed to xorriso to include on the
ISO. Stop doing that and just put the files directly into the ISO root
that is already passed to xorriso.
Package contents were being extracted into subdirectories of the boot
tree (grub_dir, shim_dir), which meant the boot tree contained both
the final boot files and the raw package extractions. Extract packages
into scratch directories instead, copying only the needed files into
the boot tree. This also removes the grub_dir/shim_dir instance
variables and the create_dirs overrides, and moves copy_grub_modules
to a standalone function in grub.py.
Set MAKE_ISO=yes so ubuntu-mini-iso uses the standard isobuilder
flow in auto/build. The binary hook is simplified to just creating
kernel/initrd artifacts; isobuilder handles .disk metadata, boot
configuration, and ISO creation.
The mini-iso's custom grub.cfg (single iso-chooser-menu entry) is
generated by a project-specific path in AMD64BootConfigurator.

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.
