ASoC: topology: KUnit: Add KUnit tests passing topology with PCM to snd_soc_tplg_component_load 
In order to ensure correct behaviour of topology API, add unit tests
exercising topology functionality.

Add topology containing PCM template and tests for parsing it. Also
adds test cases simulating modules reloads in case of separate drivers
for card and component.
