Add a standalone tool to create AHAB container for imxrt118x. This can generate a trivial unsigned image without appending ELE. The tool can be used to create bootable images for m33. To do anything more complicated, the user needs to use the official SPSDK tool from NXP. Assisted-by: Claude Code:claude-opus-5-0 Signed-off-by: Jukka Laitinen <jukka.laitinen@tii.ae>
