eff93d268a Bluetooth: BAP: Add common capability check
Instead of having 2 separate and non-equal checks for
capabilities in ASCS and the Broadcast Sink, there is now
a single function in pacs.c that performs the
check.

This reduces code size and makes it easier to maintain.

e73bfb92c7 tests: Bluetooth: ASCS: Fix various issues in ASCS unit tests
The ASCS unit tests had various errors after adding support for
dynamic registration.
Several tests did not properly clean up after failure, causing other
tests to fail when they shouldn't.

Moved the register tests to their own file as they should not
do the register in the "before" function.

The test_ascs_unregister_with_ases_in_config_state test was also
removed, as it had both issues and the state that it wants to test
cannot be reached with the current API - It is not possible to
put an ASE in the configured state without callbacks,
and registered callbacks prevents us from calling
bt_bap_unicast_server_unregister to trigger the case as that can
only be done if callbacks are unregistered. Since unregistering
callbacks also puts all ASEs to the idle state, it is not possible
to call bt_bap_unicast_server_unregister for a non-idle ASE.

The testcase.yaml was also missing some Kconfig options to
properly enable the client tests.

dc97bbd35f Bluetooth: Audio: Rename bt_audio_codec_qos -> bt_bap_qos_cfg
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.

b939e720a6 tests: source Zephyr before project() call
Fixes: #73831

find_package(Zephyr) should be called before first project() call.

Zephyr package will test and force-set the correct toolchain, especially
the C compiler.
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:
> CMAKE_C_COMPILER= /usr/bin/gcc

This cache deletion results in other errors, such as a missing BOARD
setting.

a94bfe03a4 tests: Bluetooth: Audio: Move role specific mocks files
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.

8be6db67fc Bluetooth: ISO/BAP: Refactor BIS bitfield
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).
