build: make ARCH=<arch>[,...] init installs what the tree needs

Browse Source 
One ISA or several (ARCH=amd64,aarch64,riscv64, for the full
acceptance), on Debian/Ubuntu with apt-get, sudo when not root:

- common: the build, the disk-image tools (scripts/mkdiskimage.sh;
  sfdisk is in fdisk), git-lfs for the logs and DoE CSVs, and the
  documents -- docs/book/Makefile's own list, and pdflatex, doxygen and
  graphviz for docs/formal;
- per ISA: its QEMU, its UEFI firmware at kernel/Makefile's paths, and
  its compiler (aarch64's loader also needs clang and lld-link).

Then git lfs install --local, so a log or CSV committed from this
checkout goes into LFS (the 1003 plain files fixed in 027b144e came
from a checkout without it). Not installed: syft (make sbom), which is
not packaged.

Checked on Ubuntu 24.04: init for all three ISAs, then make docs and
make -C docs/formal vols build. make -C docs/formal doxygen fails in
LaTeX on "newunicodechar Error: ASCII character requested" with every
package present -- a separate fault, not a missing dependency.
