Fix: EEVEE-Next: Lights with large radius do not work

The threshold is way too high as the light power gets very small.
It still make sense to include the power here because
some lights might be disabled for some BSDF types, and
skipping the LTC eval code can be beneficial.
So reducing the threshold to very low value near FLT_MIN
to fix the issue.
