[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.
