board: mimx93_evk_a55: add led and button definitions and alias

Tested with zephyr example project "samples/basic/blinky" and "samples/
basic/button". These examples can run out-of-the-box. No modification
needed.
for "samples/basic/blinky", the red LED inside RGB LED on board will
blink every 2 seconds.
for "samples/basic/button", the red LED inside RGB LED on board will
turn on once BTN1 on board is pressed down. An log will be present in
uart console as well.
