AthenaKernel: Extend ThinningCache to hold additional data.

ThinningCache holds a map of object keys to a set of thinned entries, and is used during output.

Extend ThinningCache so that it now olds a ThinningInfo structure, rather than just the set of thinned entries. This allows us to extend ThinningCache to hold additional information. Here, we're adding the set of vetoed variables per object.
