Espressif ESP32-S3 DevKit-1 C boards moved NeoPixel pin on board revision

Espressif moved the RGB LED. Quoting from their doc:

Both the initial and v1.1 versions of ESP32-S3-DevKitC-1 are available on the market. The main difference lies in the GPIO assignment for the RGB LED: the initial version uses GPIO48, whereas v1.1 uses GPIO38.

Creating new board defs seems like a bit of a waste. I wonder if we should alias the pins to, say, board.NEOPIXEL_V10 and board.NEOPIXEL_V11, or maybe just omit the name.

For portable (across boards) code, this would be a bummer.
board_id is how code is supposed to tell what it's running on.

I'd prefer to have new boards for these. That way the status LED will work too. We can use ccache to speed up additional board builds.
