When Qt is configured with `-qreal float`, then we should still compare QVariants containing floating point values with the full precision of the stored type, and not cast to qreal (ie. float). Cast all floating point types up to double, which is the highest- precision floating point type we support in Qt. This might have a small performance impact when compiling with `-qreal float`, if the FPU does not perform well with double-precision floating point values. We don't test any `-qreal float` configurations in CI, so not adding a unit test for this.
