Jim Mussared 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.
