Simplify the status LED to save power
This also removes the need to pin share because we don't use the
status LED while user code is running.

The status flashes fallback to the HW_STATUS LED if no RGB LED is
present. Each status has a unique blink pattern as well.

One caveat is the REPL state. In order to not pin share, we set the
RGB color once. PWM and single color will be shutoff immediately but
DotStars and NeoPixels will hold the color until the user overrides
it.

Fixes #4133
