Add report_sets option to ScheduleBuildSettings (#7756)

# Objective

- Fixes #7442.

## Solution

- Added `report_sets` option to `ScheduleBuildSettings` like described in the linked issue.

The output of the `3d_scene` example when reporting ambiguities with `report_sets` and `use_shortnames` set to `true` (and with #7755 applied) now looks like this: 
```
82 pairs of systems with conflicting data access have indeterminate execution order. Consider adding `before`, `after`, or `ambiguous_with` relationships between these:
