Vulkan: LightmapGI Bounce Indirect Energy property not implemented (unlike BakedLightmap in 3.x)

Godot version

4.0.dev (7bd7b8f)

System information

Fedora 34, GeForce GTX 1080 (NVIDIA 465.31)

Issue description

This issue is a reminder to implement #50827 in the master branch's GPU lightmapper.

If you are reading this and want to give it a try, feel free to open a pull request to reimplement it 🙂
Just leave a comment to let other people know, or to ask questions about the implementation.

Remember that this property should affect indirect lighting energy (bounced light) only. It should not affect direct light (when the light's bake mode is set to All) and emissive materials' lighting.

Steps to reproduce

• Create a LightmapGI node in the master branch.
• Select the node and look for a Bounce Indirect Energy property.

Fixed by #82068, I think this should be closed to avoid cluttering the tracker.
