When handling negative steps, start and stop need to be mp_int_t so they
can be checked against a potential negative value during the for loop
used to set the slice values.
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).

This change takes polygon from 126k pixels per second fill to 240k pps fill
on a reference 5 point star 50x66px polygon, updating both location and shape
at 10hz. Tested on an m4 express feather.
As a curiosity, the flat-out fill rate of a shape whose get_pixel is `return 0;`
fills just shy of 375k pixels per second.
When calling `AES.decrypt_into()` or `AES.encrypt_into()`, the
destination buffers may be any buffer kind. However, we currently
aren't checking to make sure the destination buffer is actually
writable.
Specify `MP_BUFFER_WRITE` for the destination buffers of both of these
objects so we don't inadvertently write to immutable data.

In order to accept both `bytes` objects and `bytearray` objects, use a
`bufinfo` construct to retrieve the data rather than
`mp_obj_str_get_data()`.
