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.
