Animate unit frame bars with ClassicAPI's SmoothStatusBarMixin

Health and power bars take SmoothStatusBarMixin instead of pfUI's own OnUpdate animation, so the animation no longer runs faster at higher frame rates. The speed dropdown becomes an on/off checkbox, since the mixin's rate is fixed. A new range keeps the bar's filled share, so it doesn't jump before the animation moves on.
