[core] Reduce presence of the 'useIntegerZoom' option

The `useIntegerZoom` presence is now limited: it is removed
from `PossiblyEvaluatedPropertyValue` class specializations
(was never used there!) and from the `PropertyEvaluationParameters`
class, so we do not have to copy `PropertyEvaluationParameters`
instance at `RenderLineLayer::evaluate`.
