boards/lckfb-szpi-esp32s3: switch adb config to nxinit entrypoint
Replace the default nsh-based init flow on the lckfb-szpi-esp32s3 :adb
defconfig with system/nxinit so that services (sh console, adbd) are
spawned and reaped by init through /etc/init.d/init.rc.
- Enable CONFIG_SYSTEM_NXINIT and set INIT_ENTRYPOINT to init_main
(CONFIG_EXPERIMENTAL is required by SYSTEM_NXINIT).
- Add a common init.rc under boards/xtensa/esp32s3/common/src/etc/init.d
defining 'console' (sh) and 'adbd' services and starting both on init.
fastbootd is wired in for completeness when configured.
- Append the new init.rc to RCSRCS only when SYSTEM_NXINIT is enabled
so existing nsh-based configs remain unaffected.
Verified on lckfb-szpi-esp32s3 hardware: init_main spawns sh and adbd
(both with PPID=init), 'adb shell' reaches a working NuttShell.
