Enable tests to turn off Windows Vista animations

Animations in that style depend on the current time, which makes it
impossible to run baseline tests. Introduce a dynamic property that
allows us to set the time that animations use.

This way, tests can turn the animation off, or control which time should
be used.

To keep performance overhead low, check only once whether the dynamic
property is set at all.
