usb: typec: tcpm: add support for Sink Cap Extended msg response

Add support for responding to Sink Cap Extended msg request. To achieve
this, include parsing support for DT properties related to Sink Cap
Extended. The request for Sink Cap Ext is a control message while the
response is an extended message (chunked). As the Sink Caps Extended
Data Block size (24 Byte) is less than MaxExtendedMsgChunkLen (26 Byte),
a single chunk is sufficient to complete this AMS.

Supporting sink cap extended messages while responding to a
Get_Sink_Caps_Extended request when port is in Sink role is required in
order to be compliant with at least USB PD Rev3.1 Ver1.8.
