LAF "drawComboBox" isPopupActive should be a separate property

[jonhallur]

From the HISE code

obj->setProperty("hover", cb.isMouseOver(true) || cb.isMouseButtonDown(true) || cb.isPopupActive());

isPopupActive should really be it's own property.

Use-case: So many UI designs have a triangle that rotates when combo box is open.

@jonhallur obj.enabled property is also not just the enabled property

obj->setProperty("enabled", cb.isEnabled() && cb.getNumItems() > 0);
