topology: Tuple type can have an extenstion

Browse source 
After the type specific string ("uuid", "string", "byte", "short" and
"word"), users may append a string, like  "uuidxxx". The topology parser
will check the first few characters to get the tuple type.

This can allow users to put multiple tuples of the same type into one
vendor tuple section (SectionVendorTuples), e.g. parameters of multiple
firmware modules.
