LP#1053397 apply org scope to metarecord attributes

When loading record attributes (cra, ccvm, etc.) for constituent
records, limit the attributes to those contained by records which have
holdings within the provided (search) scope.

With this, for example, a search at Branch 1 for metarecords will only
show format icons for constituent records that have holdings at BR1.
