Eevee: Planar Reflection: Remove distance approximation.
...
This commit separate the depth texture into another texture array.
This remove the need to output radial depth into alpha.
Unfortunatly it's difficult to recover position from the non linear depth buffer when applying reflection without adding a bunch of stuff.
This is in preparation of SSR planar reflections.

Eevee: SSR: Small fixes
...
- Encode normals for other opaque bsdf so they are not rejected by the normal facing test.
- Early out non reflective surfaces.
- Add small offset to raytrace to avoid self intersection.
- Fix fallback probes not appearing.

It's cause by degenerate triangle having normals set to (0,0,0) which may not be compressed like it should.
