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