extmod/modmachine: Provide common bindings for 6 bare-metal functions.

Browse Source 
Minor changes for consistency are:
- nrf gains: unique_id(), freq() [they do nothing]
- samd: deepsleep() now resets after calling lightsleep()
- esp32: lightsleep()/deepsleep() no longer take kw arg "sleep", instead
  it's positional to match others.  also, passing 0 here will now do a 0ms
  sleep instead of acting like nothing was passed.
  reset_cause() no longer takes any args (before it would just ignore them)
- mimxrt: freq() with an argument and lightsleep() both raise
  NotImplementedError
