Disallow construction of QPropertyBinding from a property

This would steal an existing binding from a property, which is most
likely not the intended action.
Alternatively, we could make it equivalent to
Qt::makePropertyBinding(foo), but that conflates properties with
bindings to it. On the other hand, this would avoid a potentially
source-breaking change.

[ChangeLog][Potentially Source Breaking Change] It was possible to
create a QPropertyBinding from a property; this would steal any set
binding from the property or create an invalid binding if none was set.
Use makePropertyBinding if you want to to create a binding which depends
on the property's value, or takeBinding if you want to repurpose the
property's binding.
