Per the Wio Tracker L1 schematic, it has a green LED on P1.01. Moved SimpleLed from driver/ to board layer (esp32s3.rs and wio_tracker_l1.rs) since the impl needs HAL-specific Output types. Removed driver/simple_led.rs — each board layer defines its own. RAK WisBlock remains LedDriver=() (no user LED on the core module).
