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

Define the list of tokens pertaining to effect type 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
process component based on the topology widget_setup op in ipc3_tplg_ops.
