[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.
