Add them as MICROPY_HW_LED_STATUS so that we can share reset code
for them. They aren't actually used for the status if another RGB
option is available. (But maybe they should be.)
Fixes#6717
Removes:
* AUTORESET_DELAY_MS which never did anything but was introduced
somehow.
* CIRCUITPY_BOOT_BUTTON in all but one ESP board because they all have
them. There is a default based on the strapping pins.
* BOARD_USER_SAFE_MODE_ACTION because it was all the same for boards
with boot buttons. Now the safe mode code manages the message.
