dd0bc26e65 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.

f4726735cf extmod/modbluetooth: Implement config getter for BLE rxbuf size.
Knowing the buffer size can be important, to ensure that valid data will be
received.

7ef2f65114 docs/library: Add / to indicate positional-only args in library docs.
Removes the confusion of positional-only arguments which have defaults that
look like keyword arguments.

84958a8fe1 extmod/modbluetooth: Allow setting ringbuf size via BLE.config(rxbuf=).
The size of the event ringbuf was previously fixed to compile-time config
value, but it's necessary to sometimes increase this for applications that
have large characteristic buffers to read, or many events at once.

With this commit the size can be set via BLE.config(rxbuf=512), for
example.  This also resizes the internal event data buffer which sets the
maximum size of incoming data passed to the event handler.

7aeafe2ae9 extmod/modbluetooth: Add optional 4th arg to gattc_write for write mode.
This allows the user to explicitly select the behaviour of the write to the
remote peripheral.  This is needed for peripherals that have
characteristics with WRITE_NO_RESPONSE set (instead of normal WRITE).  The
function's signature is now:

    BLE.gattc_write(conn_handle, value_handle, data, mode=0)

mode=0 means write without response, while mode=1 means write with
response.  The latter was the original behaviour so this commit is a change
in behaviour of this method, and one should specify 1 as the 4th argument
to get back the old behaviour.

In the future there could be more modes supported, such as long writes.

e873d352ad extmod/modbluetooth: Simplify management of pre-allocated event data.
The address, adv payload and uuid fields of the event are pre-allocated by
modbluetooth, and reused in the IRQ handler.  Simplify this and move all
storage into the `mp_obj_bluetooth_ble_t` instance.

This now allows users to hold on to a reference to these instances without
crashes, although they may be overwritten by future events.  If they want
to hold onto the values longer term they need to copy them.
