is Stylish Reduced Motion Enabled
Returns whether the current platform requests reduced motion.
Mirrors the system setting on supported platforms: the helper reads the MotionDurationScale of the composition's coroutine context, which Android sets to 0f when the user enables the "remove animations" system setting (and which test harnesses can control via the effectContext). On platforms that do not expose such a setting (or when the scale is 1f), the helper returns the value of LocalStylishReducedMotion, which defaults to false.
Components should consult this helper before starting decorative animations, and snap to the target state instead of tweening when it returns true (see the Stylish chip family for the reference pattern).
Return
true when the platform requests reduced motion or LocalStylishReducedMotion is set to true.
