The Python-based runners have replaced the old shell scripts. Refactor the build system accordingly: - FLASH_SCRIPT is now BOARD_FLASH_RUNNER - DEBUG_SCRIPT is now BOARD_DEBUG_RUNNER The values, rather than being the names of files, are now the names of runners in scripts/support/runner. They are still short, descriptive names like "openocd", "jlink", "em-starterkit", etc. Adjust the zephyr_flash_debug.py call and runner internals accordingly. Have each runner class report a name and the commands it can handle. This lets us move some boilerplate from each do_run() method into the common run() routine, and enables further improvements in future patches. The handles_command() method is temporary, and will be replaced by a more general mechanism for describing runner capabilities in a subsequent patch. The initial use case for extending this is to add device tree awareness to the runners. To try to avoid user confusion, abort the configuration if an xxx_SCRIPT is defined.
