topology2: add wov-detect pipeline

wov-detect pipeline contains a micsel component, a wov component
and a virtual component. micsel component accepts 2 channels audio data and
output 1 channel audio data to the wov component. wov's keyword is a clap.
The virtual component is only used by the driver, and the FW will not
know that there is a virtual component in the pipeline. The virtual
component is used to connect the pipeline to a host copier pipeline
as per drivers requirement.
