The iso_rx_qos is only used for unicast audio, as
we do not set the RX QOS for the broadcast sink, nor
can a broadcast source set RX QOS.

The `iso_qos` was only used for connected ISO, but
was placed outside of the CONFIG_BT_ISO_UNICAST
guard, such that for broadcast ISO-only it was unused.
Move the declaration and renamed to cis_iso_qos.

Rename the BT_ISO_INTERVAL_MIN/MAX to
BT_ISO_SDU_INTERVAL_MIN/MAX to avoid confusing this

Add two new parameters to bt_iso_chan_send:
sn: The packet sequence number which shall be incremeted
per SDU interval.
ts: An optional timestamp value used to synchronize SDUs.
The sequence number in the API uses a 32-bit value even though
the sequence number for the HCI command is 16-bit. This is to
properly handle wrapping of sequence numbers, which is much
easier to do with additional bits allocated.

The "iso connect" now also takes a security level option like
"iso listen", so that the central can easily encrypt

The ISO security implementation works by verifying
against the acl (bt_conn) sec_level field. The
bt_conn sec_level field is only available
if CONFIG_BT_SMP is enabled, so this commit
adds guards for all ISO security checks as well.

A CIG may be updated later to include more CIS, and thus a slist
makes more sense.
The BIG doesn't need the change, but it makes more sense to
have similar handling for both.
This change also removes the requirement that the arrays
used to create the CIG/BIG need to static.

Add the BT_ISO_SDU_BUF_SIZE which can be used to declare
the TX buffers for ISO, similar to the BT_L2CAP_SDU_BUF_SIZE
macro for L2CAP.
This also updates the ISO samples to use this as well
updating the SDU check to use
CONFIG_BT_ISO_TX_MTU/CONFIG_BT_ISO_RX_MTU without
subtracting the BT_ISO_CHAN_SEND_RESERVE to make the

The sequence number is needed in the appliaction layer to detect lost
packets in the ISO stream in cases where the timestamp is not included.
(Sequence number is mandatory to include where timestamp is optional).
The API for the public metadata have been moved to a public header file.
As the size of the ISO meta data exceeds the default 4 octets net_buf
user_data the public ISO metadata have been moved into a seperate array.
The internal metadata is still stored in net_buf user_data.
This also fixed the user_data overflow on 32 bit systems, caused by
writing the ts into user_data on index 4 to 7, which is outside the 4
allocated bytes.

Channel direction was actually a source of confusion since the spec does
actually define the data path direction from controller point of view
meaning input actually means transmit and output receive, also direction
can be configured with different QoS settings.
To make these APIs less confusing and allow QoS to be configured
independently they are now split into RX (receiving) and TX
(transmission) settings including its data path.
