As discussed in the alternative approach zephyrproject-rtos/zephyr#68494, k_panic() in POSIX mode has various shortcomings that do not provide a useful trace. Useless pointers to signal handlers or other cleanup routines are printed instead. Leverage our already existing k_sys_fatal_error_handler() and dereference a NULL pointer there when in POSIX mode. This "fails fast" and provides a complete and relevant stack trace in CI when fuzzing or when using some other static analyzer. Example of how fuzzing failure thesofproject#8832 would have looked like in CI results thanks to this commit: ``` ./build-fuzz/zephyr/zephyr.exe: Running 1 inputs 1 time(s) each.

The fuzzer engine has produced crash caused by NULL pointer read that
originated from ipc_stream_pcm_free(). The crash happens when the
pipeline of the found comp_dev does not have a source_comp and
pipeline_reset() is called for it. This commit simply adds a test
for such a situation and bails out if it is found.
