CoreUObject.Build.cs

- Make FDoubleProperty and FFloatProperty use Verse's extensional float equality semantics, and support value hashing. This should only affect comparison of NaNs: thanks to -ffast-math/fp:fast compiler flags, the previous behavior of FDoubleProperty::Identical/FDoubleProperty::Identical was for them to treat NaNs as equal to all other values. The new behavior is to treat all NaNs as equal to each other, and unequal to numbers.
