tdf#155414 gtk3 a11y: Honor gtk setting to reduce animation
Use the "gtk-enable-animations" setting [1] to determine whether
animations should be disabled, as is documented in MDN docs
for Firefox using for the "prefers-reduced-motion" CSS media
feature [2].
Note that KDE Plasma's system settings also set this Gtk preference
when taking the steps that [2] describes for reducing motion on KDE
Plasma (s. implementation in [3]):
> In Plasma/KDE: System Settings > Workspace Behavior -> General Behavior >
> "Animation speed" is set all the way to right to "Instant".
