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.
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.
