Defines a data engine query: a set of data transforms that provides data for
a list-like element in the report.
The data engine query encapsulates three types of information:
1. A data set, including computed columns together with the parameter bindings.
2. Data transforms that are defined on report items, i.e., sorting, filtering,
grouping, aggregation functions, and so on.
3. Subqueries that are contained in the current report query.
