EEVEE: Replace octahedron reflection probe by cubemap array

We implement cubemap array support for EEVEE's lightcache reflection probes.
This removes stretched texels and bottom hemisphere seams artifacts caused
by the octahedral projection previously used.

This introduce versioning code for the lightcache which will discard any
lightcache version that is not compatible.
