Add Z scaling during unfold to launcher
The unfold progresses are mapped to 0.85 - 1 range and set as a scale for launcher.
In case of multiple scale animations for workspace and hotseat, they are combined using MultiScaleProperty (e.g. opening an app while unfolding/going to all apps while unfolding). Note that this is a pretty difficult scenario to be in. If that happens, we multiply all values and bound the result between the max and min values.
Bug: 217368525
Test: atest MultiScalePropertyTest and manually
