[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 Co-authored-by: Nick Brassel <nick@tzarc.org> Co-authored-by: Nick Brassel <nick@tzarc.org>
