EEVEE-Next: Light: New light module

Compared to the previous implementation this has a limit of 65536 lights
per scene. Lights exceeding this limit will be ignored.

This also introduce fine grained GPU light culling, making rendering
many lights in a scene more efficient as long they don't overlap much.

Compatible light panels have been unhidden.

Note: This commit does not include surface evaluation, only light culling.
