* Closes https://github.com/emilk/egui/issues/7647 This collects SnapshotResults within the Harness and adds a check to enforce snapshot results are merged in case multiple Harnesses are constructed within a test. This should make snapshot updates via kitdiff/accept_snapshots.sh way more useful since it should now always update all snapshots instead of only the first one per test.
