Redefine mask of host-controlled feature bits to include only features
that are supported by the controller. This fixes a conformance test
failure where setting an unsupported host-controlled feature bit was
not rejected as it should.
Set the Connected Isochronous Streams (Host Support) bit from the host
only if unicast support is configured to avoid failures in
broadcast-only configurations.

During discovery the unicast client subscribes to the
ASCS CP characteristic. However, this was done asynchronously
at the end of the discovery, and the discovery complete
callback was called before the subscription was done.
Since the unicast client relies on the auto CCC discovery,
the actual subscription takes place a few connection intervals
after the unicast_client_ep_set_cp function was called. The
result of this is that the actual subscription was missing
when the unicast client application starts performing
BAP operations.
The change done here postpones the discovery callback
until after the CP subscription has taken place, ensuring
that the unicast client correctly receives the CP notifications
when performing BAP operations. This also allows the unicast
client to use the discovery parameter in the
bt_audio_discover_params struct, rather than yet another
discovery parameter struct, saving some memory.

The address type in the periodic adveritising sync
established event is incorrectly set to 0x01
(BT_ADDR_LE_RANDOM) when the address is a resolved one,
where it should have been BT_ADDR_LE_RANDOM_ID.
The address type has been fixed by offsetting by 2 to get
BT_ADDR_LE_PUBLIC_ID or BT_ADDR_LE_RANDOM_ID when the
address has been resolved.

When using extended advertising commands, the advertising set is not
considered to be over until we receive `BT_HCI_EVT_LE_ADV_SET_TERMINATED`
from the controller. Only then do we clear the `BT_ADV_ENABLED` flag.
The problem is that `bt_le_adv_resume` is called on connection established,
which can happen before adv set terminated, and in that case it will
early-return because `BT_ADV_ENABLED` is still set.
This change triggers `bt_le_adv_resume` when we get
`BT_HCI_EVT_LE_ADV_SET_TERMINATED`.
