Thierry Berger 26fc4c7198 Test for ambiguous system ordering in CI (#13950) ... Progress towards https://github.com/bevyengine/bevy/issues/7386. Following discussion https://discord.com/channels/691052431525675048/1253260494538539048/1253387942311886960 This Pull Request adds an example to detect system order ambiguities, and also asserts none exist. A lot of schedules are ignored in ordered to have the test passing, we should thrive to make them pass, but in other pull requests. <details><summary>example output <b>summary</b>, without ignored schedules</summary> <p> ```txt $ cargo run --example ambiguity_detection 2>&1 | grep -C 1 "pairs of syst" 2024-06-21T13:17:55.776585Z WARN bevy_ecs::schedule::schedule: Schedule First has ambiguities. 1 pairs of systems with conflicting data access have indeterminate execution order.
