charles bloom 52b23c8d20 clean up the mess caused by AlphaCoverageThresholds ...

AlphaCoverageThresholds was accidentally enabled for all textures with thresholds = {0,0,0,1}
add new Texture bool bDoScaleMipsForAlphaCoverage
to make toggling coverage processing very clear
on old Textures that don't have the bDoScaleMipsForAlphaCoverage field, we can infer the correct value except in the case that threshold = {0,0,0,1} , in that case it's impossible to tell if it's wanted or not.  There we look up a config value "EnableLegacyAlphaCoverageThresholdScaling"
Current config has EnableLegacyAlphaCoverageThresholdScaling=1
so the legacy bad behavior is maintained
