Joakim Andersson 29b13d1270 Bluetooth: doc: Add struct members to documentation build
Struct members are not always documented in the zephyr online HTML
documentation. Enable it for all Bluetooth related documentation
groups.

Connection Management
#####################
The Zephyr Bluetooth stack uses an abstraction called :c:type:`bt_conn`
to represent connections to other devices. The internals of this struct
are not exposed to the application, but a limited amount of information
(such as the remote address) can be acquired using the
:cpp:func:`bt_conn_get_info` API. Connection objects are reference
counted, and the application is expected to use the
:cpp:func:`bt_conn_ref` API whenever storing a connection pointer for a
longer period of time, since this ensures that the object remains valid
(even if the connection would get disconnected). Similarly the
:cpp:func:`bt_conn_unref` API is to be used when releasing a reference
to a connection.
An application may track connections by registering a
:c:type:`bt_conn_cb` struct using the :cpp:func:`bt_conn_cb_register`
API. This struct lets the application define callbacks for connection &
disconnection events, as well as other events related to a connection
such as a change in the security level or the connection parameters.
When acting as a central the application will also get hold of the
connection object through the return value of the
:cpp:func:`bt_conn_create_le` API.
