Add a regression test for apache/nuttx#20166 to the configdata example, which runs automatically in every sim:configdata build. After the normal configdata test loops, close the long-lived descriptor and run a full lifetime cycle on /dev/config: - mtdconfig_unregister() must succeed, - the unregistered device must no longer be openable (ENOENT), - the same MTD device must be registerable again and usable, - a final unregister must succeed, leaving the device unregistered. Before the driver fix this crashes deterministically: the old mtdconfig_unregister_by_path() freed the private device structure before closing its temporary file, so the subsequent open() faults in mm_malloc on the corrupted heap (SIGSEGV observed on sim right after unregister returns). With the fix the whole example, 934706/934706 checks included, completes cleanly. The test uses only generic configdata APIs, so it also passes unchanged under CONFIG_MTD_CONFIG_NVS, whose open/close callbacks are no-ops.
