Merge remote-tracking branch 'origin/blender2.8' into temp-eeveelightcache

Eevee: LightCache: Add back world baking support.

GPUTexture: Add GPU_texture_layers

It's actually used to get the depth size of the texture.
This is because GPU_texture_depth is already taken.

We need to clean up this API at some point.

Eevee: Light Cache: Create Probe data and share the lightcache.

The lightcache is now can shared between viewlayers. We need this to share
the lighting data with the original viewlayer with the baking layer.

The cache is still not working.

Eevee: Light Cache: Add Operator and base implementation.

Does nothing at the moment. Just create a job and search all probes in a
view layer.

Only works if copy on write is enabled.
