MLECO-6389: Conditional generic logging for framework
TensorFlow Lite Micro based logging uses the overrides for generic Arm Cortex-M CPU targets. This patch ensures that this is the case only when the framework library target is configured internally. This will allow external library targets to be provided without mandating the use of generic Arm Cortex-M target files being included in the build.
