This changes lots of files to unify `board.h` across ports. It adds `board_deinit` when CIRCUITPY_ALARM is set. `main.c` uses it to deinit the board before deep sleeping (even when pretending.) Deep sleep is now a two step process for the port. First, the port should prepare to deep sleep based on the given alarms. It should set alarms for both deep and pretend sleep. In particular, the pretend versions should be set immediately so that we don't miss an alarm as we shutdown. These alarms should also wake from `port_idle_until_interrupt` which is used when pretending to deep sleep. Second, when real deep sleeping, `alarm_enter_deep_sleep` is called. The port should set any alarms it didn't during prepare based on data it saved internally during prepare. ESP32-S2 sleep is a bit reorganized to locate more logic with TimeAlarm. This will help it scale to more alarm types. Fixes #3786
