The dumpinfo.pl script comes from buildbot.git[0] and is used to print
available targets and architectures, which are then build.
As the buildbot clones openwrt.git anyway, the script might as well live
here as it can be used for other cases as well, e.g. determining what
architectures are available when building Docker containers or show
developers an overview which architectures are used by which target.
With the dumpinfo script we could clean up the current docker
implementation which uses a single targets.yml file with some special
cases to handle target changes between snapshot and releases.[1]

GitLab supports now dynamic child piplines[2], so a parsed dumpinfo
could automatically create CI jobs to create Docker IB/SDK containers.

It's called with either the parameter `architectures` or `targets`,
showing architectures followed by supported targets or targets, followed
by the supported architectures:
$ ./scripts/dumpinfo.pl architectures
aarch64_cortex-a53 bcm27xx/bcm2710 mediatek/mt7622 mvebu/cortexa53
sunxi/cortexa53
aarch64_cortex-a72 bcm27xx/bcm2711 mvebu/cortexa72
...
$ ./scripts/dumpinfo.pl targets
apm821xx/nand powerpc_464fp
apm821xx/sata powerpc_464fp
...
In the future the `dumpinfo.pl` script could be removed from the
buildbot repository and maintained only here.
