HPCC-10835 Add suspended/activated as filters for WUListQueries

Those two filters are requested from New ECLWatch. In this fix,
the code is added to read those two filters from WsWorkunits
WUListQueriesRequest, pass them to getQuerySetQueriesSorted() in
workunit.cpp and process them as post filters.
