Panzer: Workset size in object ctors
Created by: rppawlo
@trilinos/panzer The workset size is used in the constructors for the physics_block, mesh and workset builder. Since the user builds each object individually, there is a chance that the workset size could be inconsistent across objects. This ticket is to refactor the ctors of the objects to make sure the workset size is consistent. Additionally, we should build in flexibility so that the same value is not needed for all physics blocks and evaluation types.
