Download coreboot toolchain archives into packages/<arch> before
coreboot tries to download them. This allows us to use mirrors to get
the archives. We could also update the primary source this way if it
goes down instead of patching coreboot itself (has happened for IASL).
The archive versions and digests are retrieved from the coreboot
module, so there isn't another copy of that info to maintain. That is
done in bin/fetch_coreboot_crossgcc_archive.sh, which uses the
existing fetch script to do the actual download, leveraging mirrors.
bin/fetch_source_archive.sh supports using a SHA-1 digest instead of
SHA-256, since coreboot has SHA-1 digests. It also checks if the file
already exists (deleting the coreboot directory will cause it to be
re-run, but the packages are already there and can be used from cache).
The coreboot-4.11 IASL patch is updated to delete the outdated acpica
archive digest (it already added the new one, but the old one was still
there). bin/fetch_coreboot_crossgcc_archive.sh finds the archive
version and digest from the digest files, so only one acpica file must
be present.

Use the Heads name for a package when it differs from the primary
source. E.g. musl-cross-make's archive is just <hash>.tar.gz, which
makes little sense out of context. musl-cross-<hash>.tar.gz makes
more sense for a mirror.

Try to download dependency source packages from mirrors if the primary
source fails or the archive has changed.
Move the download and verify logic to bin/fetch_source_archive.sh. The
mirror list is here, currently only
https://storage.puri.sm/heads-packages/, but others can be added. The
mirror list is randomized to load each mirror equally.
The verify logic is moved to this script too so it can fail over to a
mirror (or another mirror) if a mismatched archive is served, not just
for a failure. Makefile no longer needs to verify separately and there
are no separate .*-_verify files any more, the archive is only moved to
its final place once verified.
Add `packages` target to just fetch all needed packages for a board,
facilitates seeding a mirror.
