74c2c31811 stm32/mpbthciport: Change from systick to soft-timer for BT scheduling.
Instead of using systick the BT subsystem is now scheduled using a soft
timer.  This means it is scheduled only when it is enabled.

61d1e4b01b extmod/nimble: Make stm32 and unix NimBLE ports use synchronous events.
This changes stm32 from using PENDSV to run NimBLE to use the MicroPython
scheduler instead.  This allows Python BLE callbacks to be invoked directly
(and therefore synchronously) rather than via the ringbuffer.

The NimBLE UART HCI and event processing now happens in a scheduled task
every 128ms.  When RX IRQ idle events arrive, it will also schedule this
task to improve latency.

There is a similar change for the unix port where the background thread now
queues the scheduled task.

6077c63a45 stm32/mpbthciport: Increase char timeout of BT HCI UART.
The 2ms used previously was not long enough and it could lose HCI sync.

Also print error on tx failure to make this more obvious in the future.

ed14435a8e extmod/modbluetooth: Refactor stack/hci/driver/port bindings.
Previously the interaction between the different layers of the Bluetooth
stack was different on each port and each stack.  This commit defines
common interfaces between them and implements them for cyw43, btstack,
nimble, stm32, unix.
