OPT-4871 the multi measure result structure was introduced, the scope of this task is to actually return multi measure results for reports with multiple `configuration.aggregationTypes`.
- for each `configuration.aggregationTypes` entry on a process report, a measure result is returned on report evaluation for the following views:
- any duration report (process instance, flow node, user task)
- number variable reports
- the order of the measures in the result should correspond to the order in the report configuration
- duplicate `configuration.aggregationTypes` entries still yield only one result
