ASoC: SOF: ipc4-topology: Add support for parsing AIF_IN/AIF_OUT widgets

Add support for parsing AIF_IN/AIF_OUT type widgets in IPC4. Add all the
new required token ID's for parsing these widgets to the list of tokens in
enum sof_tokens and the definitions of the token arrays corresponding to
each of the token ID's.

Also, upgrade the sof_widget_parse_tokens() function in the common
topology parser to be able to parse multiple sets of tokens for the
audio format and copier gateway config tokens.
