The following multi-tests pass (eg with PYBD_SF6+LEGO_HUB_NO6):
ble_gap_advertise.py
ble_gap_connect.py
ble_gap_device_name.py
ble_gattc_discover_services.py
ble_gatt_data_transfer.py
perf_gatt_char_write.py
perf_gatt_notify.py
stress_log_filesystem.py
These are the same tests that passed prior to this BTstack update.
Also tested on the unix port using H4 transport.

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.
