[EGD-5580] Fix broken mute during call

The mute button during a call did not cause
any effect.

[EGD-4977] Reduce audio lag during voice call

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.

[EGD-5086] Fix voice not starting when calling

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.

[EGD-5086] Change audio device switching logic

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.

[EGD-5061] Fix lack of audio during call

Audio might have not work if audio streams
were reused. This was fixed by introducing proper
cleaning procedures.

[EGD-4978] Add Bluetooth virtual audio device

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.

[EGD-5009] Change messy callback logic in audio module

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.

[EGD-4534] Change audio data path synchronization

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.

* fix - call ear-speaker does not work
* fix - BT sink state is not stored

[EGD-4357] Improve error handling in audio (#990)

 - error code can be now returned also during
   initialization
 - fixed crash when user requested to playback
   file that does not exist

[EGD-4301] Bluetooth Audio profile support (#984)

 - implemented audio sink/source switching
 - reorganized / renamed sound events
 - moved SetBluetoothStreamData and AudioDevice instance to base Operation class
 - added audio profiles RecordingBluetoothHSP, RoutingBluetoothHSP
 - removed unused audio Profiles
 - removed redundant OutputPath and InputPath classes from CodecParamsMAX98090

[EGD-4004] audio: fix routing synchronization (#880)

Protect copying to buffers with mutex locks. Fix C style copying.

Add sanity checks to detect synchronization issues when routing.
