EEVEE: Shadow: Simplify the shadow module

Now the shadows are linked to a `Light` object. The `Light` object is
linked to an `ObjectKey` to ensure persistence and deletion tracking.

The Uniform data are packed so that there is 1 `ShadowPunctualData`
per light in a `LightBatch`. This means there is only a shadowmap
limit to the number of `Shadow` in a scene.
