ASoC: SOF: ipc4-topology: Implement tear_down_all_pipelines callback



During system suspend there is a chance that the running stream undergo
an xrun and instead of the expected SNDRV_PCM_TRIGGER_SUSPEND trigger
we will receive SNDRV_PCM_TRIGGER_STOP.

The handling of SUSPEND and STOP triggers differ that case of the later
the sof_pcm_stream_free() will be called with free_widget_list = false.
But we must make sure that all active widgets and streams are free before
entering suspend in order to be able to resume without error.

We can utilize the tear_down_all_pipelines to put the system to an expected
state and to fix the suspend/resume error.
