boards: nxp: frdm_mcxa153: add arduino labels
Added arduino_i2c, arduino_spi and arduino_header node labels
to FRDM-MCXA153 device tree board definition, allowing compatible
shield boards to be used. Also extend the board YAML file with
related support tags arduino_gpio, arduino_i2c and arduino_spi.
