Bluetooth: Host: Disconnected bonds affect `_bt_gatt_ccc.value`

[alwa-nordic]

The documentation on _bt_gatt_ccc.value specifies that only connected peers contribute to that value. But if CONFIG_BT_SETTINGS_CCC_LAZY_LOADING=n, the implementation summarizes over all stores CCC values, including (bonded) disconnected peers.

zephyr/subsys/bluetooth/host/gatt.c

Lines 2125 to 2129 in 5c7c099

	for (i = 0; i < ARRAY_SIZE(ccc->cfg); i++) {
	if (ccc->cfg[i].value > value) {
	value = ccc->cfg[i].value;
	}
	}

Expected behavior
Only connected peers should be included in the summarized value.
