Eevee: Add Glossy Reflection clamping
This enables reducing the noise comming from very bright light sources
(like a sun) that can be found in distant HDRIs.
The lost energy may be replaced manually by a sunlight that compensate the
this loss.
This clamping only concerns Reflection Cubmaps and is done on all on all
of them.
Setting to 0.0 disables it (default).
