add resetCache() to reset the cache for Neutral/Track Particle like the Vertex

Typically in the <read section of the dictionary in non-MT code we were setting the mutable variable controlling the cache to false i.e look https://gitlab.cern.ch/atlas/athena/blob/21.2/Event/xAOD/xAODTracking/xAODTracking/selection.xml#L113

Replicate the same behaviour in master , in the same as the existing Vertex_v1 idiom.
