Introduce DIAMETER_rfc5447_Templates.ttcn

Add templates for RFC 5447 MIP6-Feature-Vector. This AVP is a bitmask which as only a few bits defined in RFC 5447, with other interfaces using this AVP adding interface-specific bits in the spec of each interface.

The templates are added in a new separate file with the aim of start splitting the tons of AVPs originating from different specs in order to be able to quickly identify them and avoid confusion.
