Added a fallback parameter to
bt_audio_codec_cfg_meta_get_pref_context
as absence of pref context in BAP implicitly means a unspecified

In the case that it is absent BT_AUDIO_CONTEXT_TYPE_UNSPECIFIED
is the returned value.
While the metadata for codec cfg and codec cap are similar,
this only applies for codec cfg as per BAP.

Removes the CIS connection establishment from bt_bap_stream_start
and move the behavior to a new funciton bt_bap_stream_connect.
This has 2 advantages:
1) The behavior of bt_bap_stream_start is much more clear and more aligned
with the spec's behavior for the receiver start ready opcode.
2) It is possible to connect streams in both the enabling
and the QoS configured state with bt_bap_stream_connect as
per the spec. This allows us to pass additional PTS test cases.
To implement this new behavior, samples and tests have been updated.
The CAP Initiator implementation has also been updated
to accomodate for the change in BAP, but the CAP
initiator implementation should work the same for application, except
that it's now possible to do unicast start on ASEs in any order
(https://github.com/zephyrproject-rtos/zephyr/issues/72138).

When in the BAP unicast server role, at least PAC sink
or PAC source shall be set.
In order to fulfill this new requirement, a few other Kconfig
options had to be changed to a `depends on` from `select` to
avoid recursive Kconfig requirements. This change may require
some applications to update their configurations according
to the migration guide.
The change from `select` to `depends on` is ideal anyhow
as that is the recommended way to add dependencies.
This can checked via the combined BT_PACS Kconfig value.

The LC3 framed macros were unused.
The LC3 unframe macros only added the 7500/10000

presets.

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.

Add callbacks to the stream objects that reflects the
state of the isochronous channel. The connected callback
is called when the isochronous channel is connected, and
similarly the disconnected callback is called when it is
disconnected.
There is a special case for unicast, where if the ACL
disconnects first, then we won't get a ISO disconnect
callback. It should be assumed that the isochronous channel
is no longer valid when the BAP stream enters the idle state,
i.e. when the "released" callback is called.
The purpose of the new callbacks is to provide additional
information to the application. Especially the unicast client
can use this to determine when the stream_start function
can be called again, as there can only ever be 1 outstanding
CIS connection request at a time, but there can be multiple
GATT requests.

takes an array of streams to verify as an argument. It's more versatile
approach than having expect_bt_bap_stream_ops_released_called_twice

The function ignores the arhument list order, so that the user does not
have to predict the exact order of function calls.
