bootm: replace CONFIG_BOOTM_FORCE_SIGNED_IMAGES with helper
In preparation for allowing even CONFIG_BOOTM_FORCE_SIGNED_IMAGES=n configurations to force boot of only signed images, replace direct use of IS_ENABLED(CONFIG_BOOTM_FORCE_SIGNED_IMAGES) with a helper that queries a static variable that can be forced at runtime in a follow-up commit. No functional change.
