Added support for dynamic registration and unregistration of the
Broadcast Audio Scan Service (BASS) within the scan delegator.
This enables both scan delegator and BASS to be registered or
unregistered dynamically at runtime.

The TBS and GTBS instances can now be dynamically registered
and unregistered, which fits better for the use cases of TBS
where specific bearers can come and go depending on the
features of the device.
For example if a SIM card is inserted, then a device can
register a TBS for the provider and remove it again if the
SIM card is removed.

Any places that checked for GTBS is now always enabled
as GTBS is mandatory to support, and the Kconfig option
was removed.
Also removed a duplicate Kconfig option for TBS,
BT_TBS_SERVICE_COUNT, as it was unused.
The other Kconfig option BT_TBS_BEARER_COUNT is used
instead exclusively to set it if needed.
Since GTBS can now exist alone, it must also
support having its own calls and other values.
This means that the GTBS and TBS instances now share
the same underlying struct.

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).

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).

Add support for receiving audio data from e.g. a PC
over USB and LC3 encode it before sending it
on BAP audio streams.
This refactores the entire TX path, as it has moved
from only support the sine wave generator, to also
supporting USB.
The encoding and sending of data is now in it's own
thread, instead of relying on the system workqueue thread
and k_work items.
Several other refactors have taken place to reduce lines
of codec (such as the introduction of the bap_foreach_stream

An audio stream is unidirectional, so it's always either
TXing or RXing, so the fields can safely be moved to an
enum.
The struct now has both a is_rx and is_tx field. The reason
why two bools are being used, is that the both of them may
be false (we need 3 states).
All access to the rx and tx structs in the union shall be
