[Core] Add Raspberry Pi RP2040 support (#14877)
* Disable RESET keycode because of naming conflicts
* Add Pico SDK as submodule
* Add RP2040 build support to QMK
* Adjust USB endpoint structs for RP2040
* Add RP2040 bootloader and double-tap reset routine
* Add generic and pro micro RP2040 boards
* Add RP2040 onekey keyboard
* Add WS2812 PIO DMA enabled driver and documentation
Supports regular and open-drain output configuration. RP2040 GPIOs are
sadly not 5V tolerant, so this is a bit use-less or needs extra hardware
or you take the risk to fry your hardware.
* Adjust SIO Driver for RP2040
* Adjust I2C Driver for RP2040
* Adjust SPI Driver for RP2040
* Add PIO serial driver and documentation
* Add general RP2040 documentation
* Apply suggestions from code review
