hardware: smasung_slsi: libcamera2: add flash function

This patch is to enable flash operation for camera
The default flash mode may be disabled. Because Cameraservice can't
inform flash mode to cameraHAL. Changing flash UI is updated at
aa_aemode. but this field also includes AE_MODE_LOCKED value.
To capture image, CameraService always set this value to AE_MODE_LOCKED.
so cameraHAL can't recognize the current flash mode
