Eevee: SSR: Add support for planar probes.

Browse Source 
This add the possibility to use planar probe informations to create SSR.
This has 2 advantages:
- Tracing is less expensive since the hit is found much quicker.
- We have much less artifact due to missing information.

There is still area for improvement.
