This adds bt_gatt_read which can used to read attribute values.
Note: Attributes which values are bigger than the MTU need to be read
multiple time until the end since the stack cannot cache any data.

bt_conn_lookup_addr_le shouldn't look for the state of the connection.
bt_conn_lookup_handle should return bt_conn only if there is a handle
so if connection is in state BT_CONN_CONNECTED or BT_CONN_DISCONNECT.

To be able to make these APIs usable for apps where the calls may
happen from preemptible tasks, it's safest to return a dedicated
reference and let the caller do bt_conn_put() once its done with the

The spec says that CCC shall only be persistent accross connection for
bonded devices:
'The Client Characteristic Configuration descriptor value shall be
persistent across connections for bonded devices. The Client Characteristic
Configuration descriptor value shall be set to the default value at each
connection with non-bonded devices'.
To handle this now each configuration has a valid field indicating if the
configuration is valid.

BT_GATT_CCC uses _bt_gatt_ccc internal struct to handle peer
configurations and special helpers to read and write to minimize the
code necessary to handle CCC in the task.
Note this not yet include handling of connection and disconnection but
the idea is that the core would automatically disable the configurations
while disconnected and re-enable once peer connect back.
