Implement LED activity API similar to BOOT LED API.
Usual activity might be a file transfer with TFTP, a flash write...
User of this API will call led_activity_on/off/blink() to signal these
kind of activity.
New Kconfig are implemented similar to BOOT LED, LED_ACTIVITY_ENABLE to
enable support for it, LED_ACTIVITY_LABEL to assign the LED in DT for
activity usage and LED_ACTIVITY_PERIOD to set the blinking period.
