Syslog may be output via services such as DFX. When debugging the init component (e.g., service startup failures, including DFX-related exceptions), syslog may not be output properly. Add a debug Kconfig option SYSTEM_NXINIT_STDOUT that redirects all init log macros (init_debug/info/warn/err) to printf instead of syslog. This is useful for early boot debugging when syslog is not yet available or serial console shows no output. Introduce init_log_output() macro as the common log backend, selected at compile time between printf (with appended newline) and syslog. Signed-off-by: wangjianyu3 <wangjianyu3@xiaomi.com>
