tdf#155414 win a11y: Honor system setting to disable animations
Use `SPI_GETCLIENTAREAANIMATION`, the "client area animation
parameter [that] indicates whether the user wants to disable
animations in UI elements" [1] to determine whether
animations should be disabled.
The parameter can be set in Windows, as documented in MDN docs
for the "prefers-reduced-motion" CSS media feature [2]:
> * In Windows 10: Settings > Ease of Access > Display > Show animations in Windows.
> * In Windows 11: Settings > Accessibility > Visual Effects > Animation Effects

tdf#155414 include system "reduce animation" preferences
, this implements the Windows equivalent of what that change does for macOS.
