Light2D inside Light Occluder lights it up

Godot version:

3.2.3 Stable Official

OS/device including version:

Windows 10, RTX 2070, for both GLES2 and GLES3

Issue description:

Light Occluders light up when there's a Light2D inside of it. It should stay in shadows since it's a closed shape, or have an option to disable it while inside an occluder shape.

Steps to reproduce:

• Create a Tilemap
• Create a tileset and a tile that has a light occlusion shape
• Create a Light2D and put it inside the tile
• Tile will light up

Minimal reproduction project:

This caveat of 2D shadow rendering may be intentionally used in some existing projects, so I wouldn't change the default behavior.

Consider opening a proposal if you still need this in a project.
