West now supports a mechanism for extension commands. Use it to move the command implementations that are tightly coupled with boards and the zephyr build system back into the Zephyr repository. This patch doesn't include test cases. Those will be moved over in a subsequent patch. Signed-off-by: Marti Bolivar <marti@foundries.io>
