Update to the latest west. This includes a new 'attach' command. There are also multi-repo commands, but those won't get exposed to the user unless they install Zephyr using "west init" + "west fetch" (and not, say, "git clone"). Replace the launchers; they now detect whether zephyr is part of a multi-repo installation, and run the west code in its own repository if that is the case. This also requires an update to: - the flash/debug CMakeLists.txt, as the new west package is no longer executable as a module and must have its main script run by the interpreter instead. - the documentation, to reflect a rename and with a hack to fix the automodule directive in flash-debug.rst for now Signed-off-by: Marti Bolivar <marti@foundries.io>
