Removed the generation of broadcast id inside the stack. It is now up
to the application to generate this by itself. The CAP sample has
been modified to allow either a static broadcast, or a random one.
All of this is handled in the application.

If we get an error/rejection from the CAP acceptor when
performing the Unicast Audio Start or Stop procedure then
we need to abort the procedure and let the application determine
what the next step is.
This change triggered a corner case when connecting to multiple
CAP acceptors as the CAP initiatior. This was also fixed as part
of this.

The QoS structure is not related to a codec, but rather a
stream, and should thus not use the "Codec" name.
The BAP and ASCS specs refer to the QoS as
"QoS configuration" several places, so it is an obvious
choice for a name.
Since the structure is defined and used by BAP, the prefix
was changed from bt_audio to bt_bap.

The CAP commander used bt_audio_valid_ltv which required

need BT_BAP_STREAM to be enabled.

find_package(Zephyr) should be called before first project() call.
Zephyr package will test and force-set the correct toolchain, especially

The project() will also set the C compiler, if not set already.
If project() is called first, then conflict arises on the C compiler
selection and thus the following message is seen:
> You have changed variables that require your cache to be deleted.
> Configure will be re-run and you may have to reset some variables.
> The following variables have changed:

For the LE Audio unittests there exists a few mock files
that implement mock versions, or callbacks, for some of the
roles and features tested.
These have been moved to where they are actually used,
reducing the scope of these files.
This both allows the individual tests to implement their own
versions of it, but more importantly it prevents issues when
adding tests for these roles. For example, due to the
bap_unicast_client.c mock file, it is impossible to implement
unit tests for the unicast client, as the functions are already
defined.

Refactors teh BIS bitfield values used for ISO
and BAP.
Previously BIT(1) meant BIS index 1, which was a Zephyr choice
in the early days of ISO, as the BT Core spec did not use
a bitfield for BIS indexes.
Later the BASS specification came along and defined that
BIT(0) meant BIS index 1, which meant that we had to shift BIS
bitfields between BAP and ISO.
This commit refactors the ISO layer to use BIT(0) for Index 1 now,
which means that there is no longer a need for conversion
between the BAP and ISO layers, and that we can use a value
range defined by a BT Core spec (BASS).

Add validation of the number of ASEs in control point
write requests.
This validates that the number of ASEs
in the control point is not greater than the total number
of ASEs we support.
This also validates that the GATT MTU is large enough to
hold all the responses from the write since those can only be
sent as notifications and never be truncated.
Finally this validates and updates the size of the buffer used to
hold the responses, which may be an optimization for some builds.

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).
