topology: Add support for parsing vendor tuples

Browse source 
Vendor can define several tuple arrays in 'SectionVendorTuples', as
well as the reference to a vendor token list object.

A later patche will copy vendor tuples in ABI format to the private
buffer of its parent data object in the building phase.
