ASoC: SOF: topology: Make src widget parsing IPC agnostic

Define the list of tokens pertaining to the src widgets, parse and
save them as part of the swidget tuples array. Once topology parsing is
complete, these tokens will be applied to create the IPC structure for the
src component based on the topology widget_setup op in ipc3_tplg_ops.
