This is another tplg_parser and testbench update on the road to provide
further flexibility around supporting new modules and IPC versions.
There will more to follow.
Changes are mostly mechanical code movements i.e. moving testbench related code
to the testbench, splitting the files into per module/component files and
making some functions static and public.
