aac5a4f178 watchdog: use common_hal_watchdog_* pattern
This pulls all common functionality into `shared-bindings` and keeps
platform-specific code inside `nrf`. Additionally, this performs most
validation in the `shared-bindings` site.

The only validation that occurs inside platform-specific `common-hal`
code is related to timeout limits that are platform-specific.

Additionally, all documentation is now inside the `shared-bindings`
directory.

dbf1bef56a watchdog: support catching the timeout
With this patch, the exception can now be caught:

    import microcontroller
    import watchdog
    import time

    wdt = microcontroller.watchdog
    wdt.timeout = 5

    while True:
        wdt.mode = watchdog.WatchDogMode.RAISE
        print("Starting loop -- should exit after five seconds")
        try:
            while True:
                time.sleep(10)
                # pass # This also works for a spinloop
        except watchdog.WatchDogTimeout as e:
            print("Watchdog Expired (PASS)")
        except Exception as e:
            print("Other exception (FAIL)")
    print("Exited loop")

This prints:

    Starting loop -- should exit after five seconds
    Watchdog Expired (PASS)
    Starting loop -- should exit after five seconds
    Watchdog Expired (PASS)
    Starting loop -- should exit after five seconds
    Watchdog Expired (PASS)

This also places it under the `microcontroller` object.
