HPCC-9018 Packagemap-validate support for checking multiple queries

Add support for validating a package against a list of specific queries.  If no queries are specified
the entire target queryset is used.

Multiple queries can be specified by using the --queryid command line option multiple times, or by
using --queryids followed by a comma delimited list of queryids.
