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.

For `microcontroller.reset()`, don't manually call NVIC_SystemReset().
Instead, call the `port_reset()` in case the port wants to do any
cleanup.

This finishes the rework of the exception handler, which is once
again stored inside the watchdog timer module.
This also implements a `watchdog_reset()` that is used to disable the
RAISE watchdog, if one is enabled.

This adds an exception to be raised when the WatchDogTimer times out.
Note that this currently causes a HardFault, and it's not clear why it's
not behaving properly.

The timeout value is calculated by the common-hal layer now, so we don't
need to be quite so clever about calculating it here.

Add a field to allow specifying a timeout when initiating advertising.
As part of this, add a new property to determine if the device is still
advertising.
Additionally, have the `anonymous` property require a timeout, and set
the timeout to the maximum possible value if no timeout is specified.

Add a new parameter to the `start_advertising()` function to enable
anonymous advertising. This forces a call to `sd_ble_gap_privacy_set()`
with `privacy_mode` set to `BLE_GAP_PRIVACY_MODE_DEVICE_PRIVACY` and
`private_addr_type` set to
`BLE_GAP_ADDR_TYPE_RANDOM_PRIVATE_RESOLVABLE`.
With this, addresses will cycle at a predefined rate (currently once
every 15 minutes).

Store the RTC value in the .uninitialized section, but make sure to
flank it with some known values. That way we can determine if the RTC
value has been initialized, or if it's random uninitialized garbage.
As part of this, add a `common_hal_rtc_init()` routine to determine if
the value is correct, or reset it to 0 if it is not valid.

Allow for setting various softradio memory settings as part of a
board in order to support lower-memory configurations. If a
parameter is unspecified then the previously-defined value is used.

This adds preliminary support for the nRF52833, which is a variant of
the nRF52840 with half the RAM, half the flash, and fewer peripherals.

This gets all the purely internal references. Some uses of
protomatter/Protomatter/PROTOMATTER remain, as they are references
to symbols in the Protomatter C library itself.
I originally believed that there would be a wrapper library around it,
like with _pixelbuf; but this proves not to be the case, as there's
too little for the library to do.
