extmod/modbluetooth: Change scan result's "connectable" to "adv_type".

This commit changes the BLE _IRQ_SCAN_RESULT data from:

    addr_type, addr, connectable, rssi, adv_data

to:

    addr_type, addr, adv_type, rssi, adv_data

This allows _IRQ_SCAN_RESULT to handle all scan result types (not just
connectable and non-connectable passive scans), and to distinguish between
them using adv_type which is an integer taking values 0x00-0x04 per the BT
specification.

This is a breaking change to the API, albeit a very minor one: the existing
connectable value was a boolean and True now becomes 0x00, False becomes
0x02.

Documentation is updated and a test added.

Fixes #5738.
