QVariantAnimation: fix binding loops

Browse Source 
Rewrite the logic of the setters to use removeBindingUnlessInWrapper()
and {set}ValueBypassingBindings() calls.

The logic of both setters didn't change, because previously the
pre-existing bindings were implicitly removed when calling the
assignment operator.
The new code just makes it explicit.
