Subject: [PATCH] WPE: fix inverted prefers-reduced-motion
SystemSettingsManagerProxy::reducedMotion() negates the reduced-motion
setting, so the documented default of false reports that the user
prefers reduced motion. Every site that honours the
prefers-reduced-motion media query then disables its animations.
The negation is left over from enableAnimations(), which this function
replaced in 446267f9f445 ("[WPE][GTK] Improvements to platform media
queries (prefers reduced motion, high contrast, and dark theme)"). There
it was correct, because the value being read was the opposite setting,
WPE_SETTING_DISABLE_ANIMATIONS. Both the function and the setting
changed polarity together, so the negation has to go.
