Add Zephyr board defs for Raspberry Pi Picos
Add board defs for rpi_pico_zephyr, rpi_pico_w_zephyr, rpi_pico2_zephyr, and rpi_pico2_w_zephyr. Flash partitions (NVM at 0x180000, CircuitPy at 0x181000) match the native raspberrypi port so users can switch between ports without reformatting. Also enable MICROPY_NLR_THUMB_USE_LONG_JUMP for the Zephyr port to fix Cortex-M0+ linker relocation errors in nlr_push. Devices should enumerate but may have bugs after that. These board definitions are meant to make it easier to test the current state of the Zephyr port. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
