core/host: Add implementation for host panic
panic_set_reason() and panic_get_reason() are called from
system_common_pre_init() if CONFIG_SOFTWARE_PANIC is enabled. A followup
commit removes CONFIG_SOFTWARE_PANIC since all boards enable it, so we
need stub implementations for the host in order to successfully compile.
LOW_COVERAGE_REASON=legacy code
