utils: sofprobeclient: embed SOF probe parser for real-time demux

Integrate the sof-probes demux engine directly into sofprobeclient so
captured compressed data is parsed in real time instead of being
written to a raw file.

Log output from non-audio probe points is printed to stdout
(equivalent to sof-probes -l). Audio probe data is extracted into
buffer_<id>.wav files in the current directory. The file output
parameter is removed; sofprobeclient no longer acts as a generic
recorder.

New files copied from SOF v2.9 sources tools/probes/ with include
paths adjusted for standalone tinycompress build:
  probes_demux.c / probes_demux.h  - probe stream parser
  probes_wave.h                    - WAV header definitions
  probe_dma_frame.h                - DMA frame packet format
