AREnvironmentProbe is created as a child of XROrigin.TrackablesParent when AutomaticPlacement is set to false on start

Package: AR Foundation

-

Reproduction steps:
1. Open the “ReproProject“ project
2. Open the “Assets/Scenes/SampleScene“
3. Enter Play Mode
4. Observe the “AREnvironmentProbe“ GameObject in the Hierarchy window

Expected result: The “AREnvironmentProbe” GameObject does not exist
Actual result: The “AREnvironmentProbe“ GameObject is a child of the “XR Origin/Trackables” GameObject

Reproducible with: 4.2.10(2021.3.43f1), 5.1.5(2022.3.45f1), 6.0.3(6000.0.17f1)

    This breaks GPU instancing in scenes where only one AREnvironmentProbe is intended.

    Batch cause:
    Objects are affected by different reflection probes.

    Disabling the AREnvironmentProbe's GameObject is a workaround for XR simulation, but a permanent fix would help in preventing confusion in scene optimization.

    The expected result would actually be that no AREnvironmentProbe is created when the AREnvironmentProbeManagers's Automatic Placement flag is off in the editor.
