Even though IRQs are disabled this seems to be required on H7 Rev Y,
otherwise Systick interrupt triggers and the MCU leaves the stop mode
immediately.
This commit saves OSCs/PLLs state before STOP mode and restores them on
exit. Some boards use HSI48 for USB for example, others have PLL2/3
enabled, etc.
Rather than dealing with the different int types, just pass them all as a
single array of mp_int_t with n_unsigned (before addr) and n_signed (after
addr).

This adds `_IRQ_GET_SECRET` and `_IRQ_SET_SECRET` events to allow the BT
stack to request the Python code retrive/store/delete secret key data. The
actual keys and values are opaque to Python and stack-specific.
Only NimBLE is implemented (pending moving btstack to sync events). The
secret store is designed to be compatible with BlueKitchen's TLV store API.

This allows the application to be notified if any of encrypted,
authenticated and bonded state change, as well as the encryption key size.

Enable it on STM32/Unix NimBLE only (pairing/bonding requires synchronous
events and full bindings).

Instead of returning None/bool from the IRQ, return None/int (where a zero
value means success). This mirrors how the L2CAP_ACCEPT return value
works.
