Audio devices are created in the audio subsystem and it is not possible
to send a device to bt service upon creation.
Introduce hookable audio device factory to allow sharing bluetooth
audio device. Move audio devices from bsp to audio allowing removal of
unwanted bsp -> audio dependency.
Remove Bluetooth proxy device which turned out to be a dead end.

Reduce audio delay by reducing audio buffer size in router operation.
Audio streams are now created directly in the operations, not in the
audio service, which gives more flexibility.
Audio Buffer size is calculated based on endpoints (source, sink) and
operation capabilities. This commit also enables allocations in a
non-cacheable region of OCRAM for endpoints that use DMA for data
transport.
Introduce power-of-two operations that use built-in functions and
possibly dedicated hardware instructions of an MCU. These operations
are required by the audio stream buffer size calculation algorithm.

Due to an error in the stream's block reservation, when the stream was
full, SAI was trying to read data to an unitialized data span randomly
disabling audio channel.
Fix the problem by overwriting data after the peek position, always
returning valid data span.

Add license headers to `h`, `c` and `sql` files as this files haven't
been checked previously, script now to automatically updates current
year in existing licenses.
Due to a race condition between source and sink voice is not always
starting when calling. Introduce audio stream connections to avoid
race condition and improve handling of audio start and stop operations.

Upon hardware change event, audio profile had been switched multiple
times forcing redundant initializations of all related objects. Logic
has been optimized and prepared for further refactor. Now upon hardware
event objects are initialized exactly once.
Bluetooth audio device requires different handling than other
audio devices. The commit adds proxy device that does not
handle requests itself but instead sends requests too Bluetooth
service.
Refactor audio module to use only one callback for communication
with audio service. This also simplifies the logic and removes
necessity to define defaults for audio values in multiple places.
Refactor audio data path to fix several synchronization issues and
excessive copy operations on large memory blocks. Introduce
audio::Stream data structure to allow connecting audio source and sink
with a zero-copy capability.
Introduce system mechanisms:
- critical section guard lock needed for stream synchronization
- non-cacheable memory allocator to allocate memory for DMA safe
buffers
Update the Googletest CMake template to match the capabilities of the
Catch2 template.

Reduce firmware size by refactoring global data defined in public
headers.
Each global variable which require runtime initialization adds
initialization code to every translation unit which includes the header
where the variable is defined and declared.

Improve workers destroying by replacing sudden death with a gentle close
request.
Make (De)Init static - when creating second instance of a codec there
was a situation when destructing one instance was causing first one to
stop working, because they share common hardware resources.
* fixed choice of input for recording
* fixed vibration setting getter
* fixed response messages from a HandleStop
* improved style of using AudioMux APIs
* Moved ApplicationLauncher to separate files - declutering

There is no requirement for this functionality and it complicates the
audio subsystem.
Fix includes and cleanup minor flaws in the process of this change.
