tests/liveupdate: add in-kernel liveupdate test
Introduce an in-kernel test module to validate the core logic of the Live
Update Orchestrator's File-Lifecycle-Bound feature. This provides a
low-level, controlled environment to test FLB registration and callback
invocation without requiring userspace interaction or actual kexec
reboots.
The test is enabled by the CONFIG_LIVEUPDATE_TEST Kconfig option.
