Decouple reading/writing of Color into GenericTypeSerializer

This adds GenericTypeSerializer, which is now responsible of
serializing the Color into a stream (other types will follow), but
only for the older version of the binary format. The new version
we just write the sal_UInt32 mValue directly.

This is a start of decoupling the serialization of generic types
in tools and vcl module from the actual type, so we can in the
future replace those with basegfx variant.
