Board defines streamlining

RP2040 just needs ARDUINO_ARCH_RP2040, no need to specify individual boards.

NeoPixel-enabled Adafruit boards only needs PIN_NEOPIXEL and NEOPIXEL_POWER, which should implicitly expand and automate support for compatible microcontroller SKUs.
(Not sure if DotStar boards have an equivalent, but Adafruit doesn't seem to provide many modern MCUs with this nowadays?)
