boards/rp23xx: Add pm configurations for the Pico 2 and Pico Plus 2.

Browse source 
raspberrypi-pico-2:pm and pimoroni-pico-2-plus:pm enable the PM
standby and dormant states with the greedy governor, suspend to RAM
with the BOARDIOC_RP23XX_SUSPEND boardctl() command, and the RTC alarm.
The console receive pin (GPIO 1) wakes the chip, and the dormant state
is refused for 30 s after boot so that a debugger can attach.  The Pico
Plus 2 configuration also adds its PSRAM to the heap.
