Fix T86042 EEVEE: incorrect irradiance bake

The environment (world) irradiance wasn't correctly skipped.

EEVEE: Add ensure_valid_reflection to glossy closures

This is ported from Cycles and fixes issues with bump/normal mapping
giving weird reflections/lighting.

Fixes T81070 Specular light should be limited to normal pointing toward the camera
Fixes T78501 Normal mapping making specular artifact

EEVEE: SSR: Check reflection ray against geometric normal

This improve self intersection prevention. Also reduce the bias
that was making a lot of rays not being shoot at grazing angles.

EEVEE: Avoid old files with too many volume shadow sample being too slow

This clamp the volumetric shadow samples to the actual old max to avoid
problematic slowdown after the bugfix rB3a29c19b2bff.

EEVEE: Depth of field: Do not shrink highlights when using overblur

This fixes the issue of bokeh size being smaller when using overblur.

The additional overblur needs to be centered on the outer radius.

Fix T86138 EEVEE: Bake Indirect Lighting crash in 2.93 with older files

This was caused by a missing version check.

Fix error in rBb9e1cc931ee9

Bad copy paste...

EEVEE: Fix incorrect volumetric light shadowing

The shadowing was computed on the light distance squared,
leaking to much light since it was integrating the extinction behind
the ligth itself.

Also bump the maximum shadow max step to the actual UI values. Otherwise
we get shadowing under evaluated because `dd` is too small.
