Bluetooth: GATT: Allow Characterist to be used with bt_gatt_indicate

Browse source 
Since BT_GATT_CHARACTERISTIC now expands to 2 attributes it may be
confusing to use bt_gatt_indicate as that expects the Value attribute to
be given which is no longer visible, so this enables the user to use
the Characteristic attribute in addition to its value.

Fixes #8231
