Distribute them to their respective {ndctl,daxctl,cxl}/filter.{c,h} locations. This also removes the naming collisions for util/json.h between util/ and ndct/util/. I.e. is no longer ambiguous or subject to being shadowed by the tool local "util" directory. Unfortunately unwinding this caused a lot of code to move all at once. The benefit is that now it is clear that ndctl is the only tool that reaches across into the 'filter' and 'json' functionality of another tool (daxctl).
