Fix the stale instruction for install and add the steps for setting up
OpenVino/OpenCV to test the noise suppression model from the open model
zoo repository.

Introduce a new module that performs noise suppression. The module loads
the noise suppression model using the OpenVino Runtime plugin, processes
the input samples to produce output samples with clean speech.
CUrrently, the module is hard-coded to compile the model to be run on
the CPU only and will be extended for other devices like the NPU in the
future.

Set both ibs/obs to be based on the ALSA period_size to make sure that the
intermediate buffers are large enough.

For now, only process widgets that don't need the basecfg extension are
supported.

The topology uses passthrough pipelines for playback/capture and
supports only 48k, 2ch, 16bit format for now.

Add instructions to build sof_ep and parser_ep first to avoid dependency
issue and race condition.

The SOF ALSA plugin allows SOF topologies to be run on the host. The plugin
is still WIP with many rough edges that need refined before production
deployment, however the plugin is usable today as a rapid development
framework for SOF infrastructure and processing.
Features that are function in the current implementation
* aplay & arecord usage working today
* modules are loaded as SO shared libraries.
* topology is parsed by the plugin and pipelines associated with the requested PCM ID are loaded
* pipelines run as individual userspace threads
* pipelines can be pinned to efficency cores
* pipelines can use realtime priority.
* alsa sink and alsa source modules available.
* pipelines can block (non blocking and mmap todo)
* 16-bit playback and capture support. Other formats to be added soon
