Rationalize board header pin defines, and add partner board headers (#192)

Browse Source 
* Board definition header files for the iniital set of SparkFun rp2040 boards

* Add default PICO_DEFAULT_I2C*, allow no PICO_DEFAULT_LED_PIN, no PICO_DEFAULT_UART* (instead of -1)
Fixup SparkFun headers

* Pimoroni board headers

* Add LED related board defines PICO_CONFIGs (to pico_stdlib for now)

* more board config changes

* add Adafruit feather, itsybitsy, qtpy board headers

* add PICO_DEFAULT_WS2812_POWER_PIN define

* MOSI/MISO -> TX/RX, some UART cleanup.. make vgaboard.h defines take preference over pico.h ones

* local change to tinyusb to cope with no default LED or UART

* fix review issues
