Vulkan: Lights with energy 0 are not culled from rendering

[Calinou]

master version of #56632. I'm opening a separate issue as this needs to be implemented separately from 3.x.

Godot version

4.0.dev (8f6cba3)

System information

Fedora 34, GeForce GTX 1080 (NVIDIA 495.46)

Issue description

Lights with energy set to 0 are not culled from rendering. This means performance won't improve when you set a light's energy to 0. Instead, you need to set the light's visible property to false. This can lead to unexpectedly low performance when animating lights in and out using an AnimationPlayer.

Lights energy = 1

Lights energy = 0

Look at the FPS counter in the top-left corner and compare with the above screenshot:

Steps to reproduce

• Add any kind of 3D light node.
• Set its Energy property to 0.
• Notice performance will be the same as if Energy was set to 1.

Minimal reproduction project

test_light_hide_master.zip

The MRP has 1 DirectionalLight with shadows enabled, 6 red OmniLights with shadows enabled and 6 green SpotLights with shadows enabled.

• D: Toggle DirectionalLight's visible property.
• O: Toggle OmniLights' visible property.
• S: Toggle SpotLights' visible property.
• E: Toggle all lights' energy property between 1.0 and 0.0.
