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

Define the list of tokens pertaining to the siggen 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
tone component based on the topology widget_setup op in ipc3_tplg_ops.
