boards: shields: arduino_giga_display_shield: add LED to DT

Added is31fl3197@50 to overlay

Also updated GIGA board yaml file to say that it supports i2c

And updated sample to mention it

 After flashing, the LED starts to switch colors and messages with the current
 LED color are printed on the console. If a runtime error occurs, the sample
 exits without printing to the console.
