Adds a new abstract struct for unicast group that is
specific for CAP. The difference between this and the BAP
unicast group, is that the parameters are CAP streams and
thus ensuring that the streams in the group adhere to the
additional requirements that CAP has on top of BAP.
This also adds foreach functions for both CAP and BAP
to allow users to iterate on the streams in the
abstract groups.
Various samples, modules and tests have been updated
to use the CAP struct and API.

Removes the dependency on the host mocks for LE Audio tests.
This is done by copying the missing mocks for assert into
the audio mocks, and then always including ztest.h.
The inclusion of ztest.h is due to the fact that
arch/cpu.h does not have an appropriate header file for
ztest, and some header files depend on ARCH_STACK_PTR_ALIGN
which is usually defined by those headers in cpu.h. However
ztest.h does define this value as well, and thus needs
to be included always.

The stack will no longer implicitly set the data path
for ISO channel, and the responsibility for doing that is
now for the upper layers/applications.
This provides additional flexibility for the higher layers
as they can better control the values and timing of the data
path, as well as support removing and even reconfiguring the
data path at will.
This also removes some complexity from the stack.
This commit also fixed a inconsistency in the disconnected
handler. CIS for centrals as well as BIS were still valid
bt_iso_chan channels in the disconnected callback,
but CIS for peripherals were completely cleaned up at this
point. This issue is fixed by moving the disconnected callback
handling to before the code to cleanup the channel for
peripherals.
Since there is a difference in how you remove data paths
depending on the GAP role (central/peripheral), the
iso_info struct type has been expanded to be more
concise of which type of CIS it is.

Some GATT services and profiles define specific behavior
based on whether the remote device is bonded or not.
The internal function, bt_addr_le_is_bonded, is the
only function to do this, but it was kept internal,
and could thus not be used for those services
without including hci_core.h.
The function has been moved to the public API
so that application can determine if a remote
address is bonded or not, and has been renamed
to not use the bt_addr namespace, but rather the
bt_le.

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.

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.

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).

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.

Modify the signature of the k_mem_slab_free() function with a new one,
replacing the old void **mem with void *mem as a parameter.
The following function:
void k_mem_slab_free(struct k_mem_slab *slab, void **mem);
has the wrong signature. mem is only used as a regular pointer, so there
is no need to use a double-pointer. The correct signature should be:
void k_mem_slab_free(struct k_mem_slab *slab, void *mem);
The issue with the current signature, although functional, is that it is
extremely confusing. I myself, a veteran Zephyr developer, was confused
by this parameter when looking at it recently.
