When the broadcast sink is stopped, the sink was also
set to NULL via
default_broadcast_sink.bap_sink = NULL;
However the lifetime of the broadcast sink does not
follow the state of the streams, and it still exists
afterwards. The broadcast sink can only be terminated
(deleted) via the term_broadcast_sink command.

Two places we did not have an error check from calling

The codec configuration data from the BIS in the BASE was not
properly copied to the stream->codec_cfg, and thus it only
contained the subgroup codec configuration values.
This commit fixes that by first copying the subgroup codec
configuration to the stream, and then setting or overwriting
any fields (if they exist).
This requires that each stream have their own codec configuration
struct allocated, so this will slightly increase memory usage.
This also adds verification of the SDU size from the BIGInfo
in the ISO receive callback.

In the unicast_client_ep_notify we would always call
bt_gatt_get_mtu, regardless of whether data == NULL.
When there is a disconnection, the notify callbacks are
called with data == NULL to indicate a unsubscription.
In the case of the unicast client, this would also trigger
calls to bt_gatt_get_mtu when there is a disconnect, which
in turn would trigger a warning that ATT is not connected.
Postponing the call to bt_gatt_get_mtu fixes this.

The bt_iso_chan_send function could take an optional
timestamp by using 0 as an indicator. The issue with
this approach was that a timestamp value of 0 is valid,
and could cause potential issue with syncing streams
in a group.
To fully support transmitting with and without timestamp,
bt_iso_chan_send_ts has been introduced, which is the only
function of the two (bt_iso_chan_send being the other) that
supports timestamps.
A new function, rather than adding a boolean to the existing,
was chosen as it simplifies the individual functions as well
as making it more explicit what the function does.
Since the bt_iso_chan_send function is used by LE audio, both
the BAP and CAP send functions have similarly been updated.
Likewise, all tests and samples have been updated to use the
updated function(s), and BT_ISO_TIMESTAMP_NONE has been
removed.
