Optimize updateFastFaceRow processing by removing some TileSpec copy (#5678)

Browse source 
* Optimize updateFastFaceRow processing by removing some TileSpec copy

It permit to decrease this function from 54% runtime to 45% and reduce copy from 14% runtime to 12.5%
getTileInfo also reduced from 27% to 23%

* makeFastFace should use a const ref too

this trigger a const pointer need in the underlying function

Also fix some code style and prevent calculating 4 times the same position at a point

* Reduce a comparison cost for lights in updateFastFaceRow
