watchdog: rename module from `wdt` and move to `microcontroller`

This also places it under the `microcontroller` object.

+//| """Watchdog Timer
+//|
+//| The `watchdog` module provides support for a Watchdog Timer. This timer will reset the device
+//| if it hasn't been fed after a specified amount of time. This is useful to ensure the board
+//| has not crashed or locked up. You can enable the watchdog timer using :class:`wdt.WDT`.
+//| Note that on some platforms the watchdog timer cannot be disabled once it has been enabled.
+//|
+//| The WatchDogTimer is used to restart the system when the application crashes and ends
+//| up into a non recoverable state. Once started it cannot be stopped or
+//| reconfigured in any way. After enabling, the application must "feed" the
+//| watchdog periodically to prevent it from expiring and resetting the system.
+//|
+//| Note that this module can't be imported and used directly. The sole
+//| instance of :class:`WatchDogTimer` is available at
+//| :attr:`microcontroller.watchdog`."""
+//|
+//| Example usage::
+//|
+//|     from microcontroller.watchdog import WatchDogTimer
+//|     wdt = WatchDogTimer(timeout=2.5)  # enable it with a timeout of 2.5 seconds
+//|     wdt.feed()"""
