dave jones2 f8e134ef3c UE-148560 - Unable to bind Float variables to certain properties in Widget elements ...

Since BP floats default to double precision, we need to relax binding requirements. Most UMG widgets uses delegates that expect single-precision floats, so we need to allow float<->double conversion in the UFloatBinding layer. Without this change, we can't bind any new float variables in UMG, which makes the feature fairly useless.

The fix simply updates UFloatBinding::IsSupportedSource to allow double properties. Additionally, when we need to retrieve the underlying value, we need to inspect the property first. If it's a double, we'll perform a cast. Otherwise, it defaults to existing behavior.
